Given the population 10 top scores of Cricketer Saeed Anwer from February 1989 to June 1994 Table 2 Runs 42 126 101 | 01 110 | 01 111 60 71 70 a. Find the population variance and standard deviation of this set ofdata. b. What would be the Saeed Anwar scour on 27th percentile and 1* quartile in abovescores? c. A sample is taken from the population 126, 101, 110, 01, 71 Find the sample variance and standard deviation.
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.
