frequency (number of students)
0 1 2 3 4 5 6 7 8
number of social media posts made
how many students were surveyed?
answer attempt 1 out of 10
students

Explanation:

Step1: Identify frequencies for each post count

For 0 posts: frequency = 1
For 1 post: frequency = 2
For 2 posts: frequency = 2
For 3 posts: frequency = 5 (since the bar reaches up to 5)
For 4 posts: frequency = 2
For 5 posts: frequency = 0 (no bar)
For 6 posts: frequency = 4
For 7 posts: frequency = 3
For 8 posts: frequency = 2

Step2: Sum all frequencies

Sum = \(1 + 2 + 2 + 5 + 2 + 0 + 4 + 3 + 2\)
Calculate step - by - step:
\(1+2 = 3\); \(3 + 2 = 5\); \(5+5 = 10\); \(10 + 2 = 12\); \(12+0 = 12\); \(12 + 4 = 16\); \(16+3 = 19\); \(19+2 = 21\)

Answer:

21
