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.

  1. For the running shoe brands:
    1. __________ What is the level of measurement?
    2. __________ What is the sample size n?
    3. __________ What is the most appropriate statistic to use as a measure of the middle?
    4. __________ Considering only the brands and not the specific models, what is the value of that most appropriate measure of the middle?
    5. 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.
    6. Sketch a frequency histogram chart for the shoe brands on the back.
  2. 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.
    1. __________ What is the level of measurement?
    2. __________ Determine the sample size n.
    3. __________ Determine the minimum.
    4. __________ Determine the maximum.
    5. __________ Calculate the range.
    6. __________ Calculate the mode.
    7. __________ Calculate the median.
    8. __________ Calculate the sample mean x.
