Project – example: average annual wages in 2016 and 2020.Are they significantly different?
The research hypothesis: There are statistically significant differences in wages between the year
2016 and 2020.
The null hypothesis: the results in both groups do not differ significantly from each other
The alternative hypothesis: the results in both groups differ significantly from each other
The independent variable: year (2016, 2020)
The dependent variable: wages in selected countries.
test for dependent trials
type of analysis used for the test: Student’s t – test for dependent variables, because wages in each
country in 2020 depend on wages in 2016.
Means for every checked group are:
Test results: t =…
Significance of the test: p =… or p
