Assignment task: This is the article website:
Article: Beauty sleep: experimental study on the perceived health and attractiveness of sleep deprived people
How you would plan to analyze the expected results of the experiment
1. Estimate the means and standard deviations of the measure of the dependent variable in the treatment and control groups of the article
2. Calculate the effect size, d, you expect, given the estimated means and SDs above using the Effect Size (Cohen's d) Calculator
3. Indicate the statistical test you would use to determine if the effect was statistically significant (i.e., likely to be found in the population, not just an error due to chance), and its probability level, alpha (the probability of error).
4. using a sample size effect calculator for student t-test, calculate the sample size required to find the expected effect size statistically significant.
