Use the image to answer the question.
An illustration shows a bar graph with four bars extending vertically from the x-axis. The horizontal axis ranges from 10 to 13 in increments of 1 and the vertical axis ranges from 0 to 5 in increments of 1. The bar placed at 10 on the x-axis extends to 2 on the y-axis. The bar placed at 11 on the x-axis extends to 4 on the y-axis. The bar placed at 12 on the x-axis extends to 4 on the y-axis. The bar placed at 13 on the x-axis extends to 2 on the y-axis.
What are the values of the mean, median, and spread for the dataset shown in the bar graph?
(2 points)
Mean: (2 + 4 + 4 + 2) / 4 = 3
Median: Since there are four values, the median would be the average of the two middle values, which are 4 and 4. Therefore, the median is (4 + 4) / 2 = 4.
Spread: The range of the dataset is the difference between the highest and lowest values. The highest value is 4 and the lowest value is 2, so the spread is 4 - 2 = 2.
