Project 3 is another data colection task. Here the emphasis is on comparing the responses between some factor. See ideas below. There are several rules you MUST follow. Project details are to come, but start thinking about your idea and start producing and recording data.
(1) The data you collect must be numeric-continuous. For example, you cannot compare the number of baskets made. Baskets made are discrete values 0, 1, 2, 3, etc.
(1) Data must NOT be collected through a survey (too subjective)
(2) You my not compare the distances, times or weights of one person to another. If you are comparing distances, times, or weights, it must involve randomly selected several people or objects.
(3) You must have at least 15 obseravtions for each group you are comparing.
(4) Data values must have some variability. For example, I dont want to see someone record 15 equal values.Last year, a student compared apple weights. He said every apple weighed exactly the same. Obviously, he was using too large of a scale. He needed to use a finer unit of measure. Without natural variation, it is impossible to do any inferential statistics. Rememer, all values have natural variation, even if ever so small.
(6) The data must not exist already. It must be produced. For example, you CANNOT look up your data on the internet or from prior records, such as track times that have already been run.
(7) You may NOT compare times or scores of any video or computer game.
