Given the following students’ test scores (95, 92, 90, 90, 83, 83, 83, 74, 60, and 50), identify the mean, median, mode, range, variance, and standard deviation for the sample. SPSS is strongly recommended for this assignment. Directions are attached and tutorials may be found here:
- State your results for the sample by inserting a table from SPSS. Highlight the mean, median, mode, range, variance, and standard deviation.
- Explain which descriptive statistic is best for this data set. Why?
- Conduct a one-sample t-test and interpret the results (use a population mean of 70). Refer to the attached document for clarification.
- In what situations would this information be useful?
