3. Using the two tables of output below, write three summary statements in APA format. Be sure you report results such as Mean and SD in proper APA format. Coffee refers to the amount of money spent on coffee in the previous week, soda refers to the amount of money spent on soda in the previous week, and sleep refers to the average daily number of hours spent sleeping in the previous week. Descriptive Statistics Mean Std. Deviation 7.5500 6.1000 7.2625 coffee 9.62166 20 soda 20 20 6.79706 sleep 1.38001
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.
