Question

If you are using SPSS to conduct a two independent samples t-test, examining the impact of your independent variable of "smoking status" (smoker vs. non-smoker) on your dependent variable of "number of cavities reported in a 3 year period", the variable of "number of cavities reported in a 3 year period" would be your identified "Grouping Variable" in the Independent Samples T-Test pop up box.

True
False

Answer 1

The correct answer is "False"

Explanation:

SPSS is a software used to carry out statistical analysis on business, population growth etc.

In this scenario, the impact of smoking was analyse with the use of SPSS.

The independent variable= smoking status

Dependent variable = number of cavities reported in a 3 year period

Independent Samples T-Test is used to show the comparison between two variables after any statistical analysis.

Therefore, the variable of "number of cavities reported in a 3 year period" cannot be our identified grouping variable.
