Question No-02: The following table shows the distribution of wages per thousand employees in a certain factory. Daily Wages(RS): 22 24 26 28 30 32 34 36 38 40 42 44 No.of Employees: 3 13 43 102 175 220 204 139 69 25 6 1 Calculate the Mode, Median, Lower quartile, Upper quartile, D3, and P75. Question No.03: The following are the scores made by two batsman A and B in a series of innings. A: 12 15 6 73 7 19 199 36 84 29 B: 47 12 76 48 4 51 37 48 13 0 Who is better as a run-getter? Who is the more consistent player?
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.
