1. Calculate all measures of central tendency for data that are interval or ratio in measurement2. Calculate the standard deviation for data that are interval or ratio in measurement3. Assume this is a sample of students, calculate a t-test that compares boys and girls on the number of absences (you can assume equal variances). Is there a significant difference in absences between gender?4. Assume this is a sample of students and that students receive an A grade if their score is 90 or above.1. Calculate a chi-square test to determine whether girls achieve more A grades than boys in math.2. Calculate a chi-square test to determine whether girls achieve more A grades than boys in reading.
