Can anybody help me thee other ones I've seen on Jishka are no help but my question is
1. Find the mean of the data set. If necessary, round to the nearest tenth.
15.8. 14.9, 16.7, 17.6, 13.4
15.7
16.2
16.7
19.6
I think it's 15.7 but I can't confirm it and my dad is at work and my mom doesn't know math well, My dad knows math better than my mom so I really don't have much help at home right now.
Btw this is Unit 3 lesson 11 Connexus 6th grade I just need help with the calculations or something
You are correct
You added them up and then divided the sum by 5
to get 15.68 , which rounds to 15.7 correct to the nearest tenth.
ok Thank you!
To find the mean of a data set, you need to calculate the average of all the numbers in the set.
In this case, you have the following numbers: 15.8, 14.9, 16.7, 17.6, 13.4.
To find the mean, you need to add up all these numbers and then divide by the total number of values.
So, let's go step by step:
1. Add up all the numbers: 15.8 + 14.9 + 16.7 + 17.6 + 13.4 = 78.4.
2. Now, divide the sum by the total number of values, which is 5 in this case. 78.4 ÷ 5 = 15.68.
3. Finally, round the result to the nearest tenth. Since the next digit after the tenths place is 6, which is greater than 5, you round up. So, the mean of this data set is 15.7.
Therefore, your initial guess of 15.7 is correct. The mean of this data set is indeed 15.7.
