For the following data, what is the value of SS within ? B1 B2 A1 n = 5 M = 1 SS = 10 n = 5 M = 2 SS = 20 A2 n = 5 M = 1 SS = 10 n = 5 M = 4 SS = 20 a. SSwithin = 40 b. SSwithin = 20 c. SSwithin = 60 d. SSwithin = 10
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

A1 |
n = 5 M = 1 SS = 10 |
n = 5 M = 2 SS = 20 |

A2 |
n = 5 M = 1 SS = 10 |
n = 5 M = 4 SS = 20 |
| a. |
SSwithin = 40
