MEASURES OF CENTER: Start with the data values of 74 and 187. Identify three additional data values such that the resulting sample has a median of 70. Additional values: A. Values: 39, 180, 20 B. Values: 0, 70, 78 C. Values: 68, 69, 70 D. Values: 44, 70, ,140
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.
MEASURES OF CENTER: Start with the data values of 74 and 187. Identify three additional data values such that the resulting sample has a median of 70.
Additional values:
| A. |
Values: 39, 180, 20 |
|
| B. |
Values: 0, 70, 78 |
|
| C. |
Values: 68, 69, 70 |
|
| D. |
Values: 44, 70, ,140 |
Given,
74 and 187 are the two value in a sample have median 70 we have to find other 2 value.
