1. Grade 7 Mid Unit Quiz 1. c Solution: 7+9+11+13= 40 40/4=10
2. d Solution: Mode= 14
3. c Solution: = Range= 23
4. a Solution: (Median= 15)

2. QUESTION 5 Put numbers in order from least to greatest:
0, 0, 0, 2, 3, 4, 5, 6, 7, 8
(most common number)
Mode: 0
(largest minus smallest number)
Range: 8 – 0= 8
(Middle number of set)
Median: 3+4= /2= 3.5
(Add the numbers and then divide that by how many numbers are in the set)
Mean: = /10= 3.5

3. -3 left after canceling zero pairs
QUESTION 6
( -10) + (+7)= -3
-10
left after canceling zero pairs +7

4. +2 left after canceling zero pairs
QUESTION 7
( -3) - (-5)
add the opposite
(-3) + (+5)=
left after canceling zero pairs -3 +5

5. QUESTION 8
There are 5 numbers in the set so draw five blanks:
The median is 8 so it goes in the middle
The mode is 7 so place two sevens at the front
The median is 9
so the sum of the digits is 9 x 5 = 45
7+7+8= 22 and 45 – 22= 23 so the last 2 digits must add to 23 (ex: 10 and 13)
Our set could be: 13 7 7 8 10
