Please help me, only answer if you know for sure

Step-by-step explanation:

Median: First write in ascending order. If number of data's is odd, median is the middle data.

If number of data's is even, then median = average of n/2th and (n+2)/2th term.

1) 1 , 3 , 5 , 5 , 6

Median = 5

2) 3,4,10,2,1

Ascending order: 1,2,3,4,10

Median = 3

3) 4, 5,7,11

Median = (5+7)/2 = 12/2 = 6

4) 1,1,2,6

Median = (1+2)/2 = 3/2 = 1.5

5) 2,2,3,3,,5,7

Median = 3+3/2 = 6/2 = 3

6)1,2,4,6,7,7

Median = (4+6)/2 = 10/2 = 5

7) 2,2,3,6,7,8

Median = (3+6)/2 = 9/2 = 4.5

8)1,2,3,14,17,18

Median = (3+14)/2 = 17/2 = 8.5

Mean= Sum of all the items÷ number of items

1)Mean = (1+2+3+2)÷4 = 8÷2 = 4

2)Mean=(4+3+2+4+2)÷5 = 15÷5 = 3

3)Mean = (5+4+6+1)÷4 = 16÷4 = 4

4)Mean = (2+5+1+4+7+5)÷6 = 24÷6 = 4

5)Mean =(10+11+9+12+8)÷5=50÷5 = 10

6)Mean = (1 + 2 + (-2)+1+(-2) )÷5 = -2÷5 = -0.4

7)Mean = (4+(-2)+3+(-3)+3)÷5 = 5÷5 = 1

8)Mean = (4+5.5+3+5.5)÷4=18÷4 = 4.5

Median

1) 5

2) 3

3) 5+7=12/2=6

4)1+2=3/2=1.5

5)3+3=6/2=3

6) 4+6=10/2=5

7) 3+7=10/2=5

8)14+3=17/2=8.5

Mean

1) 2

2) 3

3)4

4)4

5) 10

6) 0

7) 1

8) 4.5

Step-by-step explanation:

Median is the middle number, make sure the list of in order from smallest to highest.

2) 1, 2, 3, 4, 10

if you have two numbers in the middle add them together then divide by 2

4) 1, 1, 2,6

5)2, 2, 3, 3, 5, 7

6) 1, 2, 4, 6, 7, 7

7)2, 2, 3, 7, 6,8

8)1, 2, 3, 14, 17, 18

Mean is when you add all the numbers together and divide by how many there are.

1) 1+3+2+2=8/4=2
