Explanation Definition: Measures of central tendency Mean: It is the ratio of sum of all the data values in a dataset to the total number of data values. The mean is usually denoted by x ¯ . If x is set of data values and n is the total number of data values, then mean is calculated by the formula x ¯ = ∑ x n Median: The central number when the numbers in the data set are arranged in ascending order. If there are two central numbers (in the case of even number of data), then the median is the mean of these two central numbers. Mode: Mode is the most repeating data value in the dataset. It is possible to have more than one mode. Calculation: The given dataset is x = ( 70 , 81 , 95 , 79 , 85 ) . Total number of data values, n = 5 . Mean is calculated as shown below:

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 tw…

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 o…

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 compar…
