I will discuss the functions and effectiveness of the hypothetical psychology test to understand the analyzation and the order for the test. In this paper I will calculate the mean score for each question, mean score for the entire test and a graph that represents the scores for each question in the form of mathematics and measurements that represent the outcomes on a visible scale.
The report is broken down by the number of students and how each student scores on their test.
The students test scores were broken down my each question one at a time. Each test item yielded two points each based on the student answers being right or wrong.

Kubiszyn & Borich, states the means has three characteristic that is measured for the central tendency most frequently used are means, median and mode (p 280). In this report the letter (M) will represent the means for this report. For this report I am using the arithmetic mean by adding the numbers and dividing the sum by the number in the data listed below in the charts. The first question provided had five questions each of the questions had a total based upon ten students.
Question one had a total of 18
Question two had a total of 14
Question three had a total of 2
