Construct a frequency distribution table for the following data: The number of hours spent by ten Grade 7 students in helping at home per day: 5, 1, 4, 1, 5, 2, 2, 3, 1, 2 The results when a die was tossed several times: 2, 1, 5, 3, 6, 3, 4, 1, 3, 4 5, 1, 6, 3, 6 The ages of the student representatives to an International Math Competition: 15, 12, 14, 14, 17, 13, 13, 15, 14, 13
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.
