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.
Construct the cumulative frequency distribution for the given data.
| Daily Low (Fahrenheit) | Frequency |
| 35-39 | 3 |
| 40-44 | 4 |
| 45-49 | 6 |
| 50-54 | 10 |
| 55-59 | 8 |
| 60-64 | 8 |
| 65-69 | 1 |
Construct the cumulative frequency distribution.
| Daily Low Temperature (Fahrenheit) | Cumulative Frequency |
