do you only do one activity, or do you do multiple activities for fun?

Answer 7

here's

Answer 8

multiples

Answer 9

ok, so if you were asked to identify what types of activities you did, would you only put down 1?

Answer 10

it is different cause is many activity's to choose from

Answer 11

so that means i have to put all activity

Answer 12

right

so what if one of the students in the question played more than one sport?

would they only put down a single sport or would the put down multiple?

Answer 13

okay

Answer 14

this would mean that a single student might have 2 or 3 x's

Answer 15

multiples sport

Answer 16

yes thank u

Answer 17

that's certainly a possibility

you need to think outside the box

Answer 18

maybe the data is wrong, or someone miscounted, or the poll is from a different class, or there were actually more than 24 students

the possibilities are endless

Answer 19
