Abstract
Given the data provided by the students from Alabama A&M University and Alabama State University, the following research was conducted. The number of hours students studied per week was gathered by questionnaires from a sample size of 20 students. The objective of this paper is to interpret all of the necessary qualitative and quantitative data and present in accurate mathematical computations and graphics. In order to do this we include all of the necessary analyses.
This report will perform the following statistical analyses:
Ø Summarize the variables under study graphically (frequency distribution, histogram, etc).
Ø Test the variables under study using descriptive statistics.
Ø Test of Hypothesis
Ø For each classified group separately summarize the variable under study using the descriptive measures.
Ø Compare the descriptive measures of the groups.
Ø Interpret and draw conclusions from each analysis.
Introduction
In this research paper, two data sets have been taken from a statistical database and have been converted into tables and charts in order to relate the data in simpler form.

They were both the top pitchers of their respective leagues and played in many all-star games. This brings up a question of which one is the better pitcher.

While comparing stats you have to remember that these two pitchers have completely different styles. Nolan Ryan was a power pitcher and Greg Maddux was a finesse pitcher. A power pitcher throws a lot of fast ball pitches that
"Starlight star bright" make me beautiful tonight. So many young girls gaze into the stars wishing that they could be beautiful so they would be accepted at school, as well as loved and acknowledged more. Pecola Breedlove in Toni Morrison's The Bluest Eye is no different than any other little girl. She too wants to be beautiful.

Monday nights were usually football nights where the same crowd would arrive talking gambling and stats. “That was a good crowd.

Sports fans loved the radio because not only could they hear live broadcast but if they missed the game they could get stats all day long.

differences between science and religion is the philosophical equivalent of comparing apples and oranges. "These are two such different things," Shermer told Sharon Begley in Newsweek's cover story "Science Finds God," "it would be like using baseball stats to prove a point in football."

Robert Nozick uses the example of Wilt Chamberlain to develop his theories on entitlement and distribution by establishing his libertarian view of justice in chapter 7 of his book "Anarchy, Stat, And Utopia" .
