The measures of central tendency are given below:That is correct!
Answer: 16 Boxes
That is correct!
Answer: median=26 thousands of dollars
That is correct!
Answer: mode=3 cards Mean: 104.25; Median: 92.5; Mode: 98. Identify the outlier and the measure of central tendency that is affected by the outlier. The outlier is 98. The mode is affected by the outlier. The outlier is 98. The mean is affected by
the outlier. The outlier is 200. The median is affected by the outlier. The outlier is 200 . The mean is affected by the outlier. Question 5
Given the following histogram, decide if the data is skewed or symmetrical.
A bar graph has a horizontal axis titled Values labeled from 2 to 18 in increments of 2 and a
vertical axis titled Frequency labeled from 0 to 200 in increments of 50. 14 bars are plotted,
above the numbers 2 to 16. From left to right, the heights of the bars are as follows: 1. 5. 10.
40, 75, 125, 190, 180, 130, 125, 60, 25,20, 10. All values are approximate.
