The distribution of weekly production (tons) of a rice mill was as follows: Class 71-80 81-90 91-100 101-110 111-120 121-130 131-140 141-150 151-160 >160 Frequency 5 15 7 10 31 13 12 6 16 7 Find the mean, median, and mode for the given data
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.
The distribution of weekly production (tons) of a rice mill was as follows:
| Class | 71-80 | 81-90 | 91-100 | 101-110 | 111-120 | 121-130 | 131-140 | 141-150 | 151-160 | >160 |
|---|---|---|---|---|---|---|---|---|---|---|
| Frequency | 5 | 15 | 7 | 10 | 31 | 13 | 12 | 6 | 16 | 7 |
