4 students measure their height. Their heights measure 184 cm, 192 cm, 164 cm, and 200 cm. What is the mean height of the studen
melomori [17]
The mean is the average, which is the sum of all the numbers divided by the total numbers there are. I will add them up for you, and then work from there.
184 + 192 + 164 + 200 = 740.
There is 740cm total, but now we need to divide by how many students we have. We have 4 students total.
740/4 = 185.
Your average (mean) height of the students is 185cm.
I hope this helps!
