Compute the standard deviation of each of the two data sets A and B below. Then subtract the Standard Deviation of the data set A from the Standard Deviation of data set B. State your result as a decimal value with one digit after the decimal point (e.g. 3.0). Data set A: 1, 2, 3, 4, 5, 6 Data set B: 21, 22, 23, 24, 25, 2
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.
Compute the standard deviation of each of the two data sets A and B below. Then subtract the Standard Deviation of the data set A from the Standard Deviation of data set B. State your result as a decimal value with one digit after the decimal point (e.g. 3.0).
Data set A: 1, 2, 3, 4, 5, 6
Data set B: 21, 22, 23, 24, 25, 26
