Question

The following data shows the number of pets for 30 students in a math class:
Pets: 0, 1, 2,3,4,5,6
Frequency:3,13,6,4,3,0,1
What is the standard deviation, to the nearest tenth?

I'm not sure how to solve for this. Thank you!

Answer 1

First find the mean of the data, \[\frac{ 3*0+1*13+2*6+3*4+4*3+5*0+6*1 }{ 30 }\]
