Given the population 10 top scores of Cricketer Saeed Anwer from February 1997 to June 2001 Table 2 Runs 108 104 95 103 63 72 105 90 88 77 a. Find the population variance and standard deviation of this set of data. b. What would be the Saeed Anwar scour on 27th percentile and 1st quartile in above scores? c. A sample is taken from the population 108, 101, 104, 63, 72 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.
