The dataset shows exercise period, measured to the nearest minute, for 25 people: 108, 139, 120, 123, 120, 132, 123, 131, 131, 157, 150, 124, 111, 101, 135, 119, 116, 117, 127, 128, 139, 119, 118, 114, and 127. 1) Construct a frequency distribution table for the dataset using five classes. The table should include class limits, midpoints, frequencies, and class boundaries. 2) Construct a histogram diagram, use the frequencies.
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.
