Choose the BEST method for the situation:

Two different methods of teaching number division in two respective samples of elementary school students were compared using a test of division ability, which was administered at the end of the study. In addition, the children were also measured at the beginning of the study on an intelligence test yielding an intelligence score. You want to know if there are differences between the two methods using the data that you have collected.

A college instructor wants to try two different teaching methods to introduce a challenging topic in class. This instructor randomly assigned students to two groups: the first group was taught using method A, and the second group using method B. After that, both groups of students took a 15-point assessment test with the following results: group A: 2, 2, 3, 3, 1, 7, 9, 10,12 group B: 4, 4, 5, 5, 6, 6, 6, 7, 8 Based on the results,...

An occupational psychologist wishes to assess two different methods of manager supervision in influencing employee productivity. One method involves constant supervision by the workplace manager, while the second method involves intermittent (every 15 minutes) supervision by the workplace supervisor. To test whether constant versus intermittent supervision may influence workplace productivity differently, the psychologist first randomly selects 8 employees at his/her organization. Over the course of two weeks, each of the n = 8 employees is exposed to each of the...

A researcher compares the effectiveness of two different instructional methods for teaching pharmacology. A sample of 51 students using Method 1 produces a testing average of 81.6. A sample of 76 students using Method 2 produces a testing average of 76.4. Assume that the population standard deviation for Method 1 is 12.24, while the population standard deviation for Method 2 is 11.19. Determine the 90% confidence interval for the true difference between testing averages for students using Method 1 and...

There were two separate children samples who were taught history in two different way, one is traditional using only blackboard the other one using different methods of teaching history including videos. The first sample has n = 10 with SS = 450 where the second sample has n = 4 and a SS = 230. Calculate the pooled variance for both samples. If the sample mean difference is 6 point, do you have the enough information for rejecting the null...
