2. find the distribution of this data using a statistic software e,g, SPSS, Minitab, MATLAB etc.
3. to answer question 2, find the word file attached to this email.
4. The two provided tables in the file are the results of a questionnaire-based survey that is repeated twice. The questioner has three questions, and the total number of respondents is 41. the study is repeated twice for testing questionnaire reliability. Tables 1 and 2 indicate the answers of 41 respondents to the questionnaire at two different times. Is the survey reliable? (the solutions on calculating reliability, must be using retesting method)
the NOTE: calculating the reliability by retesting method is usually conducted by calculating the Pearson coefficient.
