II. Solving. Solve the following problems. Show your solutions and create another table or column if necessary. 1. The following are the data collected from the heights (cm) of CIDEC's students. Create an array and frequency table with 11 as the desired number of dlass interval. 156 120 179 130 165 143 152 133 179 123 152 152 145 133 145 152 114 143 120 179 158 152 130 130 160
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.
