Can a moderator me?
find the mode:
31, 1, 12, 2, 21, 22, 1, 0, 31, 13

a, 1
b, 31
c, 1 & 31
d, no mode

The mode is the number that appears most frequent within a given sequence.

To start us off, let's make a list of the numbers and how many there are.

0 : 1
1 : 2
2 : 1
12 : 1
13 : 1
21 : 1
22 : 1
31 : 2.

Now let's see which number(s) appears the most.

1 and 31 appear the most, so 1 and 31 are our mode.

Your answer is :

C.) 1 & 31.

I hope this helps!

31, 1, 12, 2, 21, 22, 1, 0, 31, 13

Remember, the mode is the number that appears the most! :)

So, let's go through each number and see how many times they appear within this data set :)

31 : appears twice

1 : appears twice

12 : appears once

2: appears once

21 : appears once

22 : once

0 : appears once

13 : appears once

So, 31 and 1 both appear twice, therefore giving us the answer.

C) 1 & 31
