I. Directions/Instructions: Write TRUE if the statement is true and FALSE if the statement is false.
1. The measure of variability allows us to determine the spread of the data. 2. The greater the variability, the more consistent the scores.
3. In finding the range of ungrouped data, we will subtract the highest score to the lowest score.
4. In finding the range of the group data, we will subtract the highest- class mark to the lowest class mark.
5. The first step in getting the variance of grouped data is to determine the class boundary.
6. In finding the mean deviation, it is important to get the absolute value of (x-mean).
7. In finding the variance, we need to square root the result of (x-mean)
8. Standard deviation is the square root of variance.
9. The median is the middle point.
10. Variance is NOT a measure of variability.

•Directions/Instructions: Write TRUE if the statement is true and FALSE if the statement is false.
1. The measure of variability allows us to determine the spread of the data.
- TRUE
2.The greater the variability, the more consistent the scores.
-FALSE
(if the values are less consistent, it's harder to make predictions. )
3.In finding the range of ungrouped data, we will subtract the highest score to the lowest score.
- FALSE
(we simply subtract the minimum value from the maximum value.)
4.In finding the range of the group data, we will subtract the highest- class mark to the lowest class mark.
-TRUE
(group distance the highest class mark the lowest class mark)
5.The first step in getting the variance of grouped data is to determine the class boundary.
-TRUE
6.In finding the mean deviation, it is important to get the absolute value of (x-mean).
-FALSE
(in finding mean deviation we need to divide by the number of numbers within the data set)
7.In finding the variance, we need to square root the result of (x-mean)
-FALSE
8. Standard deviation is the square root of variance.
-TRUE
(standard deviation, which is simply the square root of the variance)
