Question

Find the values of the 30th and the 90th percentiles of the data. 129, 113, 200, 100, 105, 132, 100, 176, 146, 152

Answer 1

Ok, found the problem. First, list the data in ascending order. You don't have to type it in if you don't want to. It's understood what that means.

Answer 2

ok im with you

Answer 3

You have 10 data points, so each "10 per cent at a time" is one data point. The smallest # is the 10th percentile, the 3rd number is the 30th percentile, and the 9the number is the 90th percentile.

Answer 4

ok i got it 30 is 105 and 90 is 176

Answer 5

I didn't sort them, but I'll take your word for it! :-) Or I could check, do you want that?

Answer 6

Can you tell me what mean, median, and mode means I learned it years ago but i have forgot it and you dont have to if you dont want to but its up to you

Answer 7

I sorted the numbers and checked and you are right! Mean is the arithmetic average. in this case you add them all up and divide by 10. Median is sorting and then getting to the halfway point in your list. Here you have a space for your middle (5 on one side and 5 on the other), so you average data points 5 and 6. Mode is the most frequently occuring #. Here, "100" happens twice while all other points happen once, so "100" is the mode.
