There are 2 identical sets of data. The highest value of set b is 3 times than the highest value of set a. (ii) How do the means of the two data sets compare? Set B of data will have a higher mean. (iii) How do the standard deviations of the two data sets compare? Set B of data will have a higher Standard deviation. (iv) How do the box-and-whisker plots of the two data sets compare?
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.
