Question

2a.) You want to know if people's age (in years) is related to the amount of time they spend on social media (hours per week). You collect a sample of 200, and measure both variables. What kind of statistical test does this call for?

1. ANOVA
2. Independent Samples t-test
3. Correlation
4. Chi-square for independence
5. Single Mean
6. Dependent Samples t-test
7. Chi-square for goodness of fit

2b.) Then Imagine you have conducted the appropriate test for the above design, with α = .05 and p = .33. What would you conclude?

1. Age and social media activity are significantly different.
2. Age and social media activity are not significantly different.
3. Age and social media activity are significantly related.
4. Age and social media activity are not significantly related.

Answer 1

2a.) You want to know if people's age (in years) is related to the amount of time they spend on social media (hours per week). You collect a sample of 200, and measure both variables. What kind of statistical test does this call for?

Since, both variables age (in years) and the amount of time they spend on social media (hours per week) are numeric variable ( continuous ) hence the best test to be done is Correlation

c. Correlation

2b.) Then Imagine you have conducted the appropriate test for the above design, with α = .05 and p = .33. What would you conclude?

Since, the p = 0.33 > α = .05

hence the null hypothesis is not rejected

Hence,

1. Age and social media activity are not significantly related.
