It must be solved with frequency distributions. Please do not solve the question with the excel. Please solve with explanation. See attached photo for the given value. The following data; It refers to the number of customers who come to a store on a daily basis. Considering this data, answer the following 4 questions. 1. Construct the cumulative series. 2. Find the mean absolute deviation. 3. Find its Mode and Median. 4. Find the standard deviation.
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.
