Prepare a 2-3 page paper explaining the following:
· Accuracy of data input is important. What method of data input would be best for each of the following situations and explain why:
· Printed questionnaires
Keyboard; aside from avoiding uncertainty from unclear handwriting or other methods, and because "...most input data consists of letters and numbers. In addition, people are usually familiar with how to use keyboards and with the layout of the keys. Thus, little training is required for users to become familiar with keyboards"

Or an OMR or optical mark recognition.

· Telephone survey
Touch-tone (keypad) input. Also considered a keyboard by the text, so the cite still applies here for reasoning.

Or

voice recognition is best because a voice input device can be programmed to distinguish answers spoken into the receiver allowing it to all be completed by computers.

· Bank checks scanning devices that recognizes bar codes are called MICR (Magnetic Ink Character Recognition) a magnetic scanning input device. This system reads the numbers at the bottom of the checks and will mechanically make modifications to the correct accounts. A MICR input system will magnetize the information at the bottom of the check for simple interpretation.

Or

The best input for bank checks would be MICR (Magnetic Ink Character Recognition) a magnetic scanning input device. Because banks have to deal with large volume of checks they need a system that can read checks fast. This system reads the numbers at the bottom of the checks and will automatically make adjustments to the proper accounts.

Input Control

...Abstract Input controls are an integral part to any form. Input controls allow users to perform a variety of functions to ensure that input data is correct complete and secure. “Data input controls ensure the accuracy, completeness, and timeliness of data during its conversion from its original source into computer data, or into a computer application. Data can be entered into a computer application from either manual online input or by scheduled automated processing. The input control reviewer should determine the adequacy of both manual and automated controls over data input to ensure that data is input accurately with optimum use of computerized validation and editing and that error handling procedures facilitate the timely and accurate resubmission of all corrected data.” (Audit and Management Advisory Services, 2012) also instruct users that input edits should be used with a form or computer application, these input edits range from checks for invalid field lengths, invalid characters, missing or erroneous data, and corrected dates, or the use of check digits. Input data should also be controlled by the use of record counts, control totals, and event logs. The duties of input controls are to ensure data entry through authorization; in addition, these duties should be separate to ensure that no one individual input control performs multiple critical tasks.  User interface (UI) design is the first task in the systems design phase of the SCLD. One element of the UI......

Classification Accuracy

...the training input for the J48 decision tree induction algorithm and the Naïve Bayesian algorithm. Decision tree structures have been proposed extensively to organize classification schemes. During classification decision trees visualize what steps need to be taken to arrive at a classification. Decision tree begins with a root node followed by intermediate node and terminates with leaf which relates to the class label. Each node in the tree evaluates an attribute in the data and determines which the intermediate node to follow. The decision is taken is based on comparing the attribute value with a constant computed using various schemes. Decision tree induction algorithms work recursively with the selection one attribute as the root node with the root node effectively splitting the data. In order to create the smallest tree, the technique for splitting the root node must be efficient. The best split is the one that provides the best information gain. In this paper we use the j48 decision tree induction classification method. In this work the J48 algorithm is selected which gives several options related to tree pruning for reducing computing time. Pruning has the advantage of interpreting the results easily. More importantly, pruning can be used to avoid over fitting. The basic algorithm described above recursively classifies until each leaf is pure, which means that the attributes have been assigned a cl ass label accurately. This process ensures maximum accuracy on......

It is ultimately important that during the user interface design or input design stage to focus on input control, which will start with source documents that will promote data accuracy and quality. Therefore, the main objective of input design is that we ensure the quality, accuracy, completeness, and timeliness of input data happens during its conversion from its original source into computer data or it is entered into a computer application. Input controls could also be considered fail safes, which ensure that data is entered into the system correctly. We must also remember the term garbage in, garbage out (GIGO), because it will not matter how much data is enter into an information system, but the quality of the data that is outputted is important, which takes us to why it is important to input controls. Although, we could discuss several to many types of input control that can be implemented during the design process, we will focus our attention on only four, which are, the standard text box, drop-down list box, validation controls, and input masks. The first of our input controls is the standard test box and its main function is to display messages or to provide a place for the user to enter data.

Design/methodology/approach – The paper employs the concept of analyst fixed effects to control for unidentifiable individual differences. Various psychological factors, such as decision style and personality traits, are documented to impact individuals’ decision making. However, analysts’ individual differences in such psychological factors are not captured by identifiable personal attributes employed in finance literature, such as years of experience. The methodology used addresses this issue and presents a more comprehensive study of analyst forecast accuracy. Findings – The paper documents that unidentifiable analyst-specific effects are significant, and that controlling for them improves model fitting and changes the explanatory power of some of the traditionally used independent variables in the literature...

...Assignment 3: Input Controls CIS 210 – Systems Analysis and Development Ibrahim Elhag Marc Espos November 12, 2013 In the realm of input security and control, input controls allow users to perform various commands to ensure that the date is correct, complete, and cohesive. When data is entered from an application or automated process, the computer can produce an input log file that identifies and documents the data entered. As a system analyst must determine the importance of automatized and manual controls over data being transpired. Another important aspect a system analyst must determine is to promote data accuracy and quality. Overall the main purpose of this system is to serve as a checkpoint towards ensuring that the data is entered into the system correctly. One thing to consider is that there are numerous types of input controls. Also that most input controls are designed to be visual and interactive. Some of these input controls are: text boxes, drop-down list box, input masks, and validation rules. The first input control is text boxes. The standard textbox displays messages or provides a place for a user to enter data. These messages usually include entities of zip codes, addresses, cities, numbers, names, and serial codes. Once a form is submitted, a script can change the structure of a textbox. When designing a text box, the designer should implement the function called auto complete function. The purpose of......

Input Controls

...These controls are commonly referred to as input controls, according to the World Wide Web Consortium. There are many types of input controls that can be used in a web form. They help to provide a framework for the kind of data that will be submitted by users. Selecting the correct input control for a data field is critical. Text input, select box, radio button, and checkboxes are four examples of input controls. As pointed out by Ponce de Leon, most input controls are visual and interactive. There is also something called a hidden input control. They can be used to store system critical data, such as database key data, that the user does not need to interact with. Text type input controls are used to input text. They provide a single-line input field in which any text can be entered. The text type input controls are useful for form data such as names, street addresses, and user names. This data is viewable on the screen, so it ought to not be used for passwords. In user interface design, input controls are an integral part of any form and allows users to perform a variety of functions to ensure that input data is correct complete and secure. Data input controls ensure the accuracy, completeness, and timeliness of data during its conversion from its original source into computer data, or into a computer application.

Input Controls

...Input Controls Assignment 3 Roseana Clark | CIS 210 Professor Nancy Romero | 11/15/2014 Application controls are used to refer to transactions and any data that relates to the computer based application system. They should be kept specific to each application. Application controls may be manual or programmed, but are necessary in the support of record accuracy as well as data validity. These controls are used in processing, output and input. The application controls will ensure the data is complete, accurate, and valid. This is where input controls assist in maintaining these goals. An input is a graphic the server displays with the report. The function of the input control will support the data is complete, accurate, and valid. The procedures include asking the user for input, validating its format, and then passing it to the report. When you create and name an input control, you would assign a predefined data type for the user to enter. The data types will define the input, as well as any restrictions the server enforces. The server uses the predefined data type to classify and validate the data. If the data type is named and the server cannot find a parameter by the same name, when the report runs, the input control will not function. Input controls are an essential part to designing a form. They will allow the user to perform any input functions. These functions may include typing in text, or to select items from a list, or even uploading a file. ......

Memory Accuracy

...MEMORY ACCURACY: THEORETICAL MODELS AND EXPERIMENTAL VALIDATION Human memory has been on many occasions compared to the operations of a computer on the basis of their multifunctional systems. Memory is critical and plays a central role in our everyday information processes. Several models of information processes have in-time being proposed. The Atkinson-Shiffrin model (1968) is the most popular is and widely used by many memory researchers. The model indicates the transfer of information from the environment into the sensory memory which is very brief that some information is forgotten before it reaches the second storage. Short-term memory is the second temporary store which is also fragile. The short-term memory is very similar to working memory responsible for higher cognitive functioning which is also temporary. Information is then finally encoded onto the long-term memory where it is assumed to be a permanent storage for longer periods. Baddeley (2000) proposed the episodic buffer as the new forth component of the working memory model. This model was initially proposed by Baddeley and Hitch (1974) with three components, the central executive assisted by the phonological loop and the visuo-sketchpad assumed to be temporary storage faculties. The episodic buffer is assumed to play a very central role of binding features into objects and it is assumed to be a temporary limited store which links all systems together for the purposes of multi-dimensional coding (Baddeley...

Accuracy of Data Input

...Running head: ACCURACY OF DATA INPUT Accuracy of data input Intro Printed questionnaires Since we are working with a document that was created digitially, then printed on paper making it analog, the trick will be finding a method that easily converts the questionnaire's answers back to digital. Options are limited, since we would be relying on the individual's handwritten marks. The ability to scan test using scantrons has been around for a while, and has proven to be an efficient and effective way to quickly grade test. However, scantrones, or OMRs, rely on the testee to fill in bubbles using only #2 pencils. For the purposes of our questionaire, this would work, but #2 pencils would have to be supplied with the questionaire. A better method would be using OCR technology that scans and recongnizes the document based on light properties. With this method, the questionaires could be filled out using any analog input device, pencils or pens. Telephone survey Telephone surveys used to be conducted primarily by a pool of telemarketers that would use terminals to input the user's responses to questions. However, automated voice technology has enable a greater number of calls to go out that ask the user questions based on prerecorded questions. Because of this method, automated survey's rely on user input from touchtone key input, or automated voice response. Automated voice response systems has improved, but they rely on the background noice from the user’s side to be......

Input Controls

...Assignment 3: Input Controls and Restricting User Interface INPUT CONTROLS No matter how data enters an information system, the quality of the output is only as good as the quality of the input. When developing or purchasing a new system or application, it is important that the system or application has adequate input controls. “Input controls ensure the complete and accurate recording of authorized transactions by only authorized users; identify rejected, suspended, and duplicate items; and ensure resubmission of rejected and suspended items (Understanding Internal Control).” These controls are critical because a large number of errors in computer systems are the results of input errors. “Input controls will ensure that data is accurately processed through the application and that no data is added, lost, or altered during processing (Hall, 2011).” There are several types of input controls for an input design such as check digits, reasonableness checks, validity checks, and batch total control. In this paper, I will discuss these input controls more in detail. When human beings use numbers - whether keying them into computers, dialing them on telephones, or reading them and telling them to others; they tend to make certain kinds of mistakes such as entering an incorrect digit, changing the order of successive digits, or adding additional digits. These types of simple mistakes are known as transposition and transcription errors. Check digits are an input......
