Question

matching:

1. normal distribution
2. standard normal distribution
3. deviation
4. frequency distribution
5. range
6. standard deviation
7. variance
8. z - score

difference between the smallest term in the data set and the largest term in the data set
a distribution that takes on the shape of a bell curve
square root of the variance
deviation of a value (x) from the mean of the sample divided by the standard deviation
normal distribution with a mean of 0 and a standard deviation of 1
organizes data into categories called classes
difference between any value and the mean of the set
square of the standard deviation

Explanation:

1. A normal distribution is a distribution that takes on the shape of a bell - curve.
2. A standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.
3. Deviation is the difference between any value and the mean of the set.
4. A frequency distribution organizes data into categories called classes.
5. Range is the difference between the smallest term in the data set and the largest term in the data set.
6. Standard deviation is the square root of the variance.
7. Variance is the square of the standard deviation.
8. A z - score is the deviation of a value (x) from the mean of the sample divided by the standard deviation.
