Math Problem Statement

Find the​ (a) mean,​ (b) median,​ (c) mode, and​ (d) midrange for the data and then​ (e) answer the given question. Listed below are the jersey numbers of 11 players randomly selected from the roster of a championship sports team. What do the results tell​ us? 67    94    7    84    80    1    24    65    69    60    72

The mean and median give two different interpretations of the average​ (or typical) jersey​ number, while the midrange shows the spread of possible jersey numbers. B. The midrange gives the average​ (or typical) jersey​ number, while the mean and median give two different interpretations of the spread of possible jersey numbers. C. The jersey numbers are nominal data and they do not measure or count​ anything, so the resulting statistics are meaningless. D. Since only 11 of the jersey numbers were in the​ sample, the statistics cannot give any meaningful results.

Solution

Let's analyze the results:

  1. Mean: The mean jersey number is approximately 56.656.6.
  2. Median: The median jersey number is 6767.
  3. Mode: The mode (most frequent value) is 11, which appears only once, making it somewhat trivial.
  4. Midrange: The midrange (average of the minimum and maximum values) is 47.547.5.

Interpretation:

  • Correct interpretation is Option C: The jersey numbers are nominal data, meaning they serve as identifiers rather than quantities or measurements. Therefore, the resulting statistics don't provide meaningful insight into the players themselves.

Would you like more details, or do you have any questions?

Here are five related questions to explore:

  1. What is the range of the data?
  2. How does the standard deviation of the jersey numbers compare with the mean?
  3. If you added another jersey number, how would it affect the mean and median?
  4. Why is the mode not useful for this dataset?
  5. What does the midrange tell us about the spread of the jersey numbers?

Tip: For nominal data, measures like the mean or median aren't useful because they don't represent meaningful quantities.

Mathematical Concepts

Descriptive Statistics
Mean
Median
Mode
Midrange

Formulas

Mean = (sum of all values) / (number of values)
Median = middle value when data is ordered
Mode = most frequent value
Midrange = (min value + max value) / 2

Theorems

No major theorems directly apply, but the concepts are part of elementary statistics.
