The head of the math department compared the scores of students in two classes on the Chapter 2 test. He found that the mean sco
re of both classes was the same. He also found that there was greater variability in the scores of Ms. Biren’s students than in the scores of Mr. Hayes’s students. Which quality of the data sets would lead the department head to that conclusion? The median score in Ms. Biren’s class is greater than the median score in Mr. Hayes’s class.The median score in Ms. Biren’s class is less than the median score in Mr. Hayes’s class.The range of scores in Ms. Biren’s class is greater than the range of scores in Mr. Hayes’s class.The range of scores in Ms. Biren’s class is less than the range of scores in Mr. Hayes’s class.
he range of scores in Ms. Biren’s class is greater than the range of scores in Mr. Hayes’s class.
Step-by-step explanation:
The range is one measure of variability. The larger the range is, the greater the distance is between the lowest and the highest values; this means the data with a greater range is more variable, and the data with a lower range is less variable.
Since Ms. Biren's class has a higher range, this means her class has greater variability.
Ok so first you turn 2 Yards into feet because the answers are all in feet by multiplying by 3/1 so it would look like this 2/1x3/1 which is 6 then you use proportion to get the 6 yards by it self so it would look like this 48/6 6/6 the you would get x= 8 feet to get 8 feet you dividied 48 by 6 hope this helps
