Pick a city in Maryland and determine the average high temperatures for each month. Record this in a table.
a. Create a box-and-whisker plot for the data.
b. What is the median temperature?
c. 75% of the temperatures are below what value? How do you know? d. 75% of the temperatures are above what value? How do you know? e. What conclusions can you draw about the temperature in Maryland?
City: Baltimore, Maryland
Average High Temperatures for Each Month:
- January: 43°F
- February: 47°F
- March: 56°F
- April: 66°F
- May: 75°F
- June: 84°F
- July: 89°F
- August: 87°F

Box-and-Whisker Plot:
___________________

------|---|-----|-|-----

Median temperature: 72°F
75% of the temperatures are below 84°F. This can be determined because 84°F is the third quartile value in the box-and-whisker plot.
75% of the temperatures are above 47°F. This can be determined because 47°F is the first quartile value in the box-and-whisker plot.
Based on the data and box-and-whisker plot, we can conclude that temperatures in Maryland generally range from around 47°F to 84°F throughout the year, with the median temperature being 72°F. There is a clear increase in temperatures from January to July, followed by a gradual decrease from August to December.
