a) What is the population of interest? Approximately, how many people are in the population of interest? (Recall, the definition of a population is: The collection of all outcomes, responses, measurements, or counts that are of interest.)

b) What is the best data collection method to use for the study (explain)? (Recall, data collection methods are: Observation, Survey, Experiment, Simulation).

c) For one of the three studies, a census is possible. Determine which one and then explain why a census is possible for that study and is not possible for the other two studies. (A census means that we are able to collect data from every unit in the population. Most of the time the population is too large for a census to be feasible)

d) For the two studies where a census is not possible, how many people, students, or cars would you sample out of the population? What sampling technique would you use (see section 1.3)? (Explain your reasoning)

The What is the population of interest are:

  • GMC students
  • People who own Cars in Macon, GA.
  • People who eat oatmeal in Georgia.

The data collection method according to the group below

  1. Survey
  2. Survey
  3. Experiment

What is the statistical studies about?

The best data collection method for the first one oatmeal  and GMC students is survey because the population is large and opinions may differ.

The best data collection method for the cars  is Experiment as one needs to study the cars that pass the red lights

For one of the three studies, a census is possible in the first one because the study population is the Georgia which is very large.

For the two studies the one that a census is not needed is GMC students and cars at red light because the population is not too big.

Based on the study I will use 500 people, 200 students, or 300 cars and the  sampling technique would be Systematic sampling, Simple random sampling and Judgmental/purposive sampling.

A  Simple random sampling is known to be the easiest method of selecting a sample as every member is known to have an equal chance of being selected in the sample.

Consider the following statistical studies:

1. A study (in Georgia) of the effect of eating oatmeal on lowering cholesterol.

2. A study of current GMC students next career move after graduating or transferring from GMC.

3. A study of how many cars run the red light at a certain intersection in Macon, GA.
