A sample of difference scores from a repeated-measures experiment has a mean of MD = 4 with a standard deviation of s = 6..
- If n = 4, is this sample sufficient to reject the null hypothesis using a two-tailed test with α = .05?
- Would you reject H0 if n = 16? Again, assume a two-tailed test with α = .05.
- Explain how the size of the sample influences the likelihood of finding a significant mean difference.
