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.
To translate 5 units left, add 5 to every x
to move up 10 units, add 10 to whole equaiotn example
y=2x+2
move left 5
y=2(x+5)+2
move up 10
y=2(x+5)+2+10
When vinegar, an acid, is mixed with baking soda, a base, the reaction is similar to the reaction of Alka-Seltzer and water; a salt, water and carbon dioxide are produced.
