To find the mean you add all the numbers then divide the sum by how many numbers there are :
1)Ford School
21+19+20=60
there are 3 numbers in the equation so you divide 60 by 3 :
60÷3=20
the mean for Ford School is 20
2)Carter School
41+36+37=114
there are 3 numbers in the equation so you divide 114 by 3 :
114÷3=38
the mean for Carter School is 38
hope this helps
Answer:
Mean=2.53
median=2
mode=2
range=3
Step-by-step explanation:
1, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 4, 4, 4
MEAN
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
38/15=2.53
MEDIAN
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
MODE
Mode is the value or values in the data set that occur most frequently.
RANGE
18-15=3
