2) The median and mode
3) Only the total sum of scores
4) The range and interquartile range

Answer 5

The sample size and standard deviation

Question 6

What is a key guideline for reporting descriptive statistics?

1) Always round to the nearest whole number
2) Report values to two decimal places

Report values to two decimal places

Question 7

What is the first step in analyzing data using SPSS?

1) Create visual graphs
2) Import the dataset and define variable types
3) Interpret the output tables
4) Generate a histogram

Answer 7

Import the dataset and define variable types

Question 8

Why should SPSS tables not be pasted directly into lab reports?

Answer 10

Standard deviation (SD)

Question 11

What is the correct format for reporting the results of a statistical test in text?

1) Include all decimals and raw data
2) Report the mean, SD, and relevant test statistics with two decimal places
3) Provide only the p-value for the test
4) Copy and paste the output table into the results section

Answer 11

Report the mean, SD, and relevant test statistics with two decimal places
