Tia, Bill, Kay, and Marco counted the number of fireflies they saw each day for a week in the summer. They each put their numbers in order from least to greatest. Tia: 9, 12, 15, 18, 21, 24, 27 Bill: 3, 6, 8, 18, 20, 21, 22 Kay: 14, 15, 16, 18, 24, 27, 32 Marco: 2, 6, 10, 14, 18, 22, 26 Whose data is skewed left? A. Tia's data B. Bill's data C. Kay's data D. Marco's data
To determine whose data is skewed left, we need to look at the distribution of each set of data. Skewed left means that the tail of the distribution is longer on the left side, indicating that there are more lower values.
Looking at Tia's data, we can see that the numbers steadily increase from 9 to 27, with no outliers or extreme values on the lower end.
Looking at Bill's data, we can see that the numbers range from 3 to 22. While there are a couple of lower values, the majority of the data is spread out evenly.
Looking at Kay's data, we can see that the numbers range from 14 to 32, with a large number of values on the higher end.
Looking at Marco's data, we can see that the numbers range from 2 to 26. The data increases steadily, but there are no extreme values on the lower end.
Based on these distributions, it appears that none of the data sets are skewed left. Therefore, the answer is none of the above, and the correct option is E) None of the above.
