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.

For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all.  Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...

I am doing a biology research project where I collected data on different birds visiting a bird feeder. The data I collected was: 13 sparrows, 10 finches, 7 cardinals, 5 robins, 5 chickadees, and 4 bluejays. I want to pose the question "Is one species more likely to visit the feeder than the others?" or "Does one species visit the feeder more than the others?" What kind of statistical test would I use to do this? (ex: chi-square goodness of...
