For the data set: 1 2, 3, 4, 5 the average or mean is 3, but the sum of the square of the deviations from the mean is: a. 1 b. 5 c. 2 d. 10 e. 7
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.
For the data set: 1 2, 3, 4, 5
the average or
from the mean is:
| a. |
1 |
|
| b. |
5 |
|
| c. |
2 |
|
| d. |
10 |
|
| e. |
7 |
