What conclusions can you draw about the temperature in Maryland?
Answer:
The median temperature for Baltimore, MD is 74.5 degrees.
75% of the temperatures are below 83.25 degrees. I know this because the third quartile is 83 and 25% of the temperatures are above 83.
75% of the temperatures are above 55.75 degrees. I know this because the first quartile is 55 and 25% of the temperatures are below 55.
Based on the box-and-whisker plot and the data, we can see that the temperature in Maryland varies throughout the year, with higher temperatures in the summer months and lower temperatures in the winter months. Overall, it seems to have a relatively moderate climate.
