The first table lists the running shoe brands I have used since 1999. Ignore the model names for this part of the quiz. Use only the brand names.
- For the running shoe brands:
- __________ What is the level of measurement?
- __________ What is the sample size n?
- __________ What is the most appropriate statistic to use as a measure of the middle?
- __________ Considering only the brands and not the specific models, what is the value of that most appropriate measure of the middle?
- Make a single frequency table including the shoe brands, frequency, and relative frequency. Ignore the specific models. Put the brands frequency table on the back.
- Sketch a frequency histogram chart for the shoe brands on the back.
- On Wednesday evening I went to the state track and ran 15 laps, 6090 meters in lane two. The variable is the lap times. I timed each lap in seconds. The lap times are recorded in the table in the order in which I ran them. Use only the lap times for the following questions.
