Question

- Calculate the median and range

of the data in the dot plot. Then
compare the results to the dot
plot for Exercise in Example 2.

Answer 1

To calculate the median, sort the numbers and find the middle value. The range is found by subtracting the lowest value from the highest. A comparison to Example 2 requires analyzing both datasets' medians and ranges.

Step-by-step explanation:

Before we calculate the median and range of the dataset, it's important to understand what these terms mean. The median is the middle number in a sorted list of numbers, which divides the data into two halves. The range is the difference between the highest and lowest values in the dataset.

For the given dot plot data, we do not have the specific values to calculate the median and range. However, assuming we had the accurate data, we would proceed as follows:

1. Sort the list of numbers in ascending order.
2. Find the median by identifying the middle value or the average of the two middle values if the dataset contains an even number of observations.
3. Determine the range by subtracting the smallest value from the largest value in the dataset.

To compare the results to another exercise, such as the dot plot for Exercise in Example 2, we would need to analyze the respective medians and ranges for both datasets. A comparison would help us understand the dispersion and central tendency of both sets of data, but without the specific values from the Example 2 dot plot, a detailed comparison cannot be completed.

Answer 2

i’m not sure but here’s a method that might help: write out the numbers least to greatest, the dots each represent one number, then remember that you add and divide for the mean( add up all the numbers then divide them by how many dots there are) and for median it’s the middle number, if there’s two in the middle add them and divide it by 2
