Descriptive Statistics
Descriptive Statistics Paper Descriptive Statistics Paper In research, the need to accurately produce results is imperative to efficient research. Team C’s hypothesis of what generates champion teams needs many tools provided in research to achieve a true answer. Team C has further simplified the meaning of champion team to any team whose team dynamics cause the team to have a winning season. With that being said, this paper will be focused on the research tools needed and the results provided by the tools to answer what stats are important for teams in the MLB to win games and eventually be champions.
Measures of Central Tendencies Even when dealing with enormous sets of data it is important to get an idea by looking at the measures of central tendency. The first three that will be looked at are mean, median, and mode. Mean is “a measure of central tendency that offers a general picture of data without inundating one with each of the observations in a data set” (Sekaran, p. 396, para 3). A more common term for mean is average. The median is “the central item in a group of observations when they are arrayed in ascending or descending order” (Sekaran, p. 396, para 5). Mode is the “most frequently occurring phenomenon” (Sekaran, 396, para 6). The following table shows the mean, median, and mode for the four sets of data that Team C will be researching: Wins, Salary, Total Season Attendance, and Team Earned Run Average.
|Measures of Central Tendencies |
| |Wins |Salary |Total Season |Team Earned Run |
| | | |Attendance |Average |
|Mean |81 |73,063,563 |2,496,458 |4.28 |
|Median |81 |66,191,417 |2,523,082 |4.20 |
|Mode |95
