The principal of a particular school received a report on the number of students enrolled (per day) in the last 45 days. 68 89 81 92 63 83 88 75 93 89 71 87 58 82 70 85 86 86 97 88 90 84 59 99 71 90 94 97 79 78 68 74 85 91 76 90 95 100 83 84 101 95 86 104 66 Directions A: Direction1. Construct a Frequency Distribution Table for the above-given data. 1.1 Provide the title for the table and write 1 as the table number. 1.2 Fill-in Column 1 Class Interval. Use 10 class intervals. Column 2 Class Boundaries Column 3 Class Marks Column 4 Frequency 1.3 Show solutions for finding the range, class size, and the lowest class mark.
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.
