Usability Testing Report

Reliability is most commonly used to refer to the degree of consistency with which measurement can be conducted, and it focuses primarily on the instruments used in research. In this most simple consideration of reliability, a researcher must demonstrate that an instrument yields consistent results. The attributes of instruments must not produce variability in research outcomes that could be misconstrued as changes to the variables being measured. Two common data collection methods are referred to in this paper: Surveys and interviews. The data collection instrument for a survey could be a written questionnaire, while the data collection instrument for an interview could be a protocol for the interviewer or a video filmed while the research participant was being interviewed. For example, consider a questionnaire used to survey people about their use of tobacco. If the questionnaire language did not differentiate among the various forms of tobacco that people us, the lack of clarity and specificity of the survey instrument could evoke inaccurate responses from participants. These inaccuracies could mistakenly be attributed to the research variables.

Two experimental procedure hinged on questioning residents or university students to answer a face-to-face survey (Abdullah et al. 2014; Yang and Wyckoff 2010).

Participants completed our survey that was available online through Qualtrics where our independent variables were embedded in the survey. We did not have to control our environment to receive valid performance scores. Our method for this assignment was through a convenience sample since it “relies on data collection from population members who are conveniently available to participate in study (Dudovskiy, John)”. We had the ability to send out the links to our survey and the participants were able to complete it at their discretion.

172). The relationship between the research design and data collection is dynamic, and the surveys purpose could have some influence on the type of survey model used. If there are problems in the collection of information the design can be changed. That is when the type of survey can be considered to decide if they should use face-to-face, telephone, or mailed surveys. According to O’Sullivan, Rassel, and Berner (2008), “respondents may ignore questionnaires that seem biased,” and “respondents’ perception of a built-in bias may largely center on the appropriateness of the response categories” (p. 179).

According to the International Organisation for Standardization (1998), the usability testing mode is used to measure the effectiveness, efficiency, responses (Bastien, 2010) and satisfaction among the users. Usability testing is carried out to measure the performance of user while using the app. The app is the prototype that will be tested. The measurement of the performance includes

Prior to contacting and collecting data from the participants, approval will be sought from the Northcentral University’s (NCU) Institutional Review Board (IRB). The participants will be contacted by phone and email and asked to identify potential participant leaders within their organization. Contact information, preferably email addresses, will be collected from the participants. One participant will be selected from each participant organization. An informed consent will be obtained from each participant, which will be a brief explanation of the study and assurance to the participants of their voluntary participation, anonymity, and confidentiality. Participants will be encouraged to answer to the best of their ability, but will be assured that they may feel free

Data was collected during the online survey and added to a spreadsheet. The order of questions were given in the order provided below in a open-question model with room for comments

In order to have a more productive outcome in our study, we must first investigate what limited our research. The sample size of people that took our survey was rather small, and 125 survey takers may not be enough to show a measurable statistical difference. The number of survey takers used in the study could be dictated by the type of research problem that is under investigation. Since our sample size may have been too small, it was difficult to find significant relationships from the data. This is due to the fact that surveys and other statistical tests require a large sample size. Since our study is quantitative research, the sample size is more relevant than those of a qualitative study.

Setting up a usability test involves carefully creating a scenario, or realistic situation, wherein the person performs a list of tasks using the product being tested while observers watch and take notes. Several other test instruments such as scripted instructions, paper prototypes, and pre- and post-test questionnaires are also used to gather feedback on the product

There are a number of reasons why software testing with real users ' views are important, even if the software is still being developed. One of the main reasons is that testing can bring value to the end product. Software testing demonstrates that defects are detected in the application that was developed. The process validates and verifies the software in order to ensure that the product meets the highest business and technical requirements that directed its design and development in the first place. The stakeholders involved in development or purchasing of software spend tremendous amount of resources in doing so and tend to want the software testing efforts to succeed and ensure that a quality product be produced. Hence, it is important for them to test the software in order to validate their implementations.

Choosing a survey method requires comparing data needs against the advantages and disadvantages of the methods available in each situation (Cooper & Schindler, 2014). Personal interviews, telephone surveys, and self-administered questionnaires all have positives and negatives in the amount, style, and timeliness of information provided. Therefore, in order to obtain the needed data, the advantages and disadvantages of each method should be considered, such as in the examples to follow.

This chapter sets out the results of survey, the analysis, and critical discussion of the findings. The data have been collected from 80 respondents. The analysis and discussion are supported by the relevant literature from Chapter 2 in order to ascertain if the findings disprove or support the existing literature.

When conducting a research report there are 2 approaches that can be used when gathering primary information. The quantitative research approach involves gathering information from a large quantity of people and composing this into a research. The result deduced from the sample is used as a means to portray the general behavior and status of the entire population of that specific area. (Studymode.com, 2011)

This chapter describes the importance of a questionnaire and presents the process for developing questionnaires and observational forms. Guidelines for questionnaire construction are provided at each stage of the process. In addition, commonly used scaling techniques and use of questionnaires in experimentation are discussed and the design of observational forms is presented.1

The questionnaires were distributed between sixth and seventh Avenue, the names of persons who the questionnaires were given to were recorded. Each respondent was given two weeks to answer the questionnaire. After the given time was up the researcher was fortunate to collect all questionnaires from each respondent.
