@helpyourmathstat Год назад

I am glad to see it helped you!! ^_^

@degifsiffir8893 2 года назад

you have to use this formula in order to get number of classes, Number of class / k / = 1+3.332log of n, n means number of observation Then k = 1+3.332 log 50 , log50= 1.698 .Therefore, k= 1+3.332 x 1.698= 1+5.65 = 6.65. Finally, round this decimal number which gives us 7. So, number of class is 7

@ETORNAM_S_HAVEN 2 года назад

hi what if your numbers at the classes part are single values, how do you find the midpoint please

@helpyourmathstat Год назад

Then you can use a weight mean distribution. It means you organize each value with its frequency. In this case, you do not need to find a midpoint.

@arelimagana6961 3 года назад

I had another question for the classes on the last part how did you find the high number. I did not understand that part.

@user-lk5tv4ld5f 3 года назад

For the midpoint part you said the way you get the answer is you did 4+15 divided by 2 and when I insert that in the calculator it gives me 11.5 not 9.5. Am I missing a step?

how does this work? Midpoint column you said 4+15 / 2 = 11.5 (not 9.5 as you have ) ?

how we can calculate 1+3.322log of n?

@boseayeni8261 Год назад

That’s the formula for getting the CI the n in the formula means count all the numbers giving together which is 50 . Put this 50 where the n is and look for the LOG of 50 E.g 1+3.322(log50) 1+3.322(1.698) 6.64 round it up 7,,

one question, when your figuring out the last class do you add 12 or 11 to 76? You said add 12 to 76 but instead you added 11. Please explain.

@@footz975 Let's count our fingers from 1 to 10. There are TEN fingers, but 1 + 10 = 11. We need to count the number 76, therefore, we add 11 to count 11 more numbers. There are a total of 12 numbers. Enjoy the holidays! - Prof. Xin
