Mrs. Jen and Miss Berry, two 4th grade teachers, didn’t want to be outdone by Raskin and Bobbins, so they challenged them to fill in the remaining data below about their 4th grade classes and their students’ ice cream preferences. See if you can fill in all of the missing pieces in the diagrams below. For these students as well, they had to choose one topping, but could not choose both.
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.
