Math Problem Statement
Solution
The sample size of the data set can be determined by adding the frequencies from the histogram. Based on the image, here are the frequencies:
- 200-205: 2
- 205-210: 4
- 210-215: 8
- 215-220: 12
- 220-225: 10
- 225-230: 4
- 230-235: 2
Adding these values gives: .
Thus, the sample size .
Would you like a deeper dive into interpreting histograms or exploring related concepts? Here are 5 follow-up questions for your consideration:
- How can we calculate the mean of a data set using a histogram?
- What is the mode based on this histogram?
- Can this data set be classified as normally distributed? Why or why not?
- How do histograms compare to other data visualization tools?
- What are potential outliers in this histogram?
Tip: When analyzing histograms, always ensure the total of frequencies matches the expected sample size for accuracy!
