Question

the graph below represents data that was collected by students on the number of social media posts they made the previous day.
social media posts
how many students were surveyed?

Explanation:

Step1: Identify frequencies for each post count

For 0 posts: 2 students; 1 post: 2; 2 posts: 1; 3 posts: 2; 4 posts: 1; 5 posts: 1; 6 posts: 5; 7 posts: 0; 8 posts: 3; 9 posts: 2; 10 posts: 3.

Step2: Sum all frequencies

Sum = \(2 + 2 + 1 + 2 + 1 + 1 + 5 + 0 + 3 + 2 + 3\)
Calculate step - by - step: \(2+2 = 4\); \(4 + 1=5\); \(5 + 2 = 7\); \(7+1 = 8\); \(8 + 1=9\); \(9+5 = 14\); \(14+0 = 14\); \(14+3 = 17\); \(17+2 = 19\); \(19+3 = 22\).

Answer:

22
