A researcher finds the following: t = 1.40, p = .20, d = .25. Which one of the following is a correct interpretation of these values?
The assumption of equal variances has not been met.
There is a statistically significant difference.
There is about one-quarter of a standard deviation difference between the means.
There is a weak positive relationship.
Homework Answers
As the p-value= 0.20, there is no statistical significant difference.
Cohen's d formula is:
As d= 0.25, there is about 0.25 or one quarter of standard deviation difference between the means
Hence, Correct option: C)

Using R, code the following: The data set `normtemp` (**UsingR**) contains body measurements for 130 healthy, randomly selected individuals. The variable temperature contains normal body temperature data and the variable gender contains gender information, with male coded as 1 and female coded as 2. First, split the data by 'gender'. If the conditions for a two-sample t-test are met then perform the correct t-test to test if the population means (by gender) are equal. Make sure you run the correct...

A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (? = 1050). The 16 students who attend the preparation course average 1200on the SAT, with a sample standard deviation of 100. On the basis of these data, can the researcher conclude that the preparation course has...
