To determine the mean and median of the data represented in a dot plot regarding the number of hours calculus students studied for exams, I would need to analyze the distribution of the data points represented in the dot plot—and unfortunately, I am unable to see images or visualize the plot itself. However, I can guide you through the process of how to find the mean and median.
-
Finding the Mean:
- Add all the data points together.
- Divide the total by the number of data points.
-
Finding the Median:
- Arrange the data points in ascending order.
- If the number of data points is odd, the median is the middle number.
- If the number of data points is even, the median is the average of the two middle numbers.
Once you have the mean and median calculated, you can then compare them to choose the correct statement from the options given:
- If the mean is less than the median, select "The mean of the data set is less than the median."
- If the mean is greater than the median, select "The mean of the data set is greater than the median."
- If the median is 3.5, select "The median is 3.5."
- If the mean equals the median, select "The mean of the data set is equal to the median."
Please calculate the mean and median based on the plot you have, and you will be able to select the correct statement accordingly. If you have specific numerical data from the plot, feel free to share it, and I can help you calculate the mean and median directly!
