Mr. Daniels was comparing two random samples of students test scores from his Advanced Algebra 1st and 3rd Block classes: 1st Block: Mean= 73.4; Standard Deviation= 6.5 3rd Block: Mean= 67.5; Standard Deviation= 12.4 What can Mr. Daniels most accurately conclude between overall class test scores of 1st and 3rd block?

1st block students tend to have a slightly better grasp of the material since the mean is higher and dispersion from the mean is less than 3rd block

The students in both classes performed the same on the test.

3rd block's scores had a higher standard deviation, so they performed much better than 1st block

3rd block scores are more closely grouped around the average, therefore they had better scores than 1st block

Mrs. Littleton made a comparison of Geometry quiz scores in her second and fourth block classes: 2nd Block 4th Block mean............82 82 standard deviation....5.7 8.3

There was greater variation in scores for 4th block.

The average score was lower for 4th block.

The average score was greater for 4th block.

There was less variation in scores for 4th block.

Here is a data set: {45, 54, 60, 39, 40, 121} Using the 1.5 IQR rule, determine if mean is skewed by an outlier.

Yes, 121 is an outlier, and the mean is skewed to the right

Yes, 39 is an outlier, and the mean is skewed to the left

No, there are no outliers, and the mean is not skewed.

No, 121 and 39 are both outliers, so the mean is not skewed.
