Question 1075817: You are a primary researcher. Select a topic of interest. Form a research question that you will ask 25 people. The question should generate a range of quantitative data. Some examples are: “ On average, how many minutes a day do you spend texting?” or “ How many inches tall are you?”
Note: Research question should start with “How often…” or, “On average, how many…” Do not ask a question like, “Do you like chocolate?” because responses are “yes” or “no.” You need numbers.
Note: Be specific. Do not ask “How many bottles of water do you drink?” Instead ask, “On average, how many 8-oz. glasses of water do you drink in a day?” You need to collect numerical data. Your question should be clear, concise and unbiased. Part of your Discussion Board posting this week will be your research question. Your research question must be approved by instructor.
Required:
1. List your raw data results in a column in Excel.
2. Construct a relative frequency distribution of your data. Remember each class should have the same width, for example classes of 0 to 5, 6 to 10, 11 to 15 etc.
3. Using Excel, calculate the mean and standard deviation of your distribution
and interpret their meanings.
4. Calculate a 95 percent confidence interval for the mean of your distribution using the t-distribution and your sample standard deviation.
5. Comment on your results – what have you observed? This is important so think and write carefully
