1.Select a topic of interest to you and record the topic in your posting, for example: “What is the average number of hours people watch TV every week?” Make sure the question you ask will be answered with a number, rather than answers with words. •What is the average number of hours per week that the ACRO Athletes spend training at the gym? 2.Write a hypothesis of what you expect your research to reveal. Example: Adults 21 years and over watch an average of 2.5 hours of TV per day. •ACRO Athletes spend on average of 5 hours weekly training at the gym. 3.Sample at least fifteen people and record their data in a simple table or chart; study the examples from Section 12-3.

4.You can gather your data at work, on the phone, or via some other method. This is your “Sampling Design.” Which of the four sampling techniques best describes your design? •The sample that I am using represents the Cluster Sample •A Cluster Sample is when an intact group of people represents the population and issued for a sample (Bluman, 2005). 5.Explain in moderate detail the method you used to gather your data. In statistics this venture is called the “Methodology.” •I went to my daughters ACRO team practices at ALL STARS. •I talked with the athletes or their parents to find out how many hours per day they spend training at the gym. •After speaking with them, I then recorded my information and came to the conclusion, that the ACRO athletes spend on Average of about 4.8 hour’s weekly training at the gym. 6.Make sure you break your sample into classes or groups, such as males/females, or ages, or time of day, etc. •My chart was broken up into 4 group or sets

1.The Women’s Trios
2.The Women’s Pairs
3.The Men’s Pair
4.The Mixed Pair

7.Calculate the mean, median, and mode for your data as a whole. •The mean would be the sum of hours spent training at the gym by each athlete per day then add each value together •18.5 + 18.5 + 18.5 +10.5 + 30 = 96

Then I would divide the sum total by 20 for each athlete or parent I spoke with •96 / 20 = 4.8 hours on average each athlete trains per week •To find the median I need to rearrange my data in order from the lowest to highest amount of hours spent at the gym. •10.5 + 18.5 + 18.5 + 18.5 + 30 = 96

The midpoint is 18.5
Therefore, the median is 18.5
The mode is the value that occurs most often in the data set. •Therefore, the mode is 18.5
8.Now calculate the mean, median, and mode of each of your classes or groups.
