Mean, Median, Mode, Range
The average of a set of numbers is called?
the mean.
How much percent is between the minimum value and the first quartile?
25%
In the set of numbers, what is the mean?
set = 5, 4, 5, 3, 5, 2
The mean is 4
You can calculate the mean from a dot plot. True or False
True.
The mode is the average of all the numbers.
False. That is the mean.
The middle value of an ordered set of numbers is called?
the median.
The largest value in the data set.
What is the maximum.
In the set 25, 30, 50, 30, 50, 30, 21 what is the range?
50 - 21 = 29
How do you find the the range on the dot plot
Subtract the max value and the min value.
The median is the number that repeats the most.
False. That is the mode.
The value that occurs the most in a data set is called?
the mode.
The smallest number in the data set.
What is the minimum.
Ms Bayardo likes to play soccer. In 5 games she scored 3 goals, 2 goals, 0 goals, 3 goals, and 1 goal. What is the average goal per game?
She averages 1.8 goals per game.
How do you find the mode on a dot plot.
The mode is the number that repeats the most, so the one with the most dots.
To calculate the mean of the set 2, 3, 2, 5, 6, you have to add all the numbers and then divide it by 5.
True
The difference between the maximum value and the minimum value is called?
What is the range.
You need 5 key components for a box plot. What are they?
Smallest value, Quartile 1, Median, Quartile 3, Largest value.
MAD
15, 17, 23, 19
2.5
True or false. You need box and whiskers to draw a dot plot.
False
In the data set 1,1,1,3,5,6,6,7,10, the range is 9.
True.
Calculate the median of the data set below: 4, 5, 3, 2, 5, 6, 7
median is 5.
Min = 2 Max = 15 Median = 5 Q1 = 3 Q3 = 6
What is the range?
13
Find MAD
76.8, 68.7, 37.6, 57.9,57.1
10.5
How do you find the median in a dot plot.
You find the middle dot by crossing them out from the outside.
In the data set: 15, 16, 18, 20, 24, 24, 42, 44, 56, 61, there is no mode.
False. The mode is 24
