You are a very good teacher . Thank you for explaining step by step. My Stat teacher isn't this good at explaining or taking it step by step. She seems to think we students are all Math geniuses or Statisticians. SD is one of my challenging areas. Thank you for breaking it down.

[@cynthiawilliamsst.johnheal7195]

This was one of the best examples I have seen and practiced so far....Thank you!!!! The only part I am having difficulty with is when I solve for SD at the end how do I get number if I am not allowed a calculator in the exam. I notice you hit the sq root key. Awesome!!!!! Thank you again.

[@mathhomeworkhelp7575]

Thank you..let me know if I can help you

[@cynthiawilliamsst.johnheal7195]

@@mathhomeworkhelp7575 Yes, quick question and thank you for responding. The final step of SD how do I square without a calculator, when you got the final answer 9.79. Thank you again. Your presentation is awesome. Have a good day!

[@mathhomeworkhelp7575]

@@cynthiawilliamsst.johnheal7195 you will need a calculator for square root otherwise you will just approximate it..the basis definition of square root is this: Square root of a times square root of a is equal to a. A square root of anything when you multiply it by itself it will gives you back the number inside the square root. Square root of 9.79 is equal to 3.something because 3 point something times 3 point something equals 9.79..hard to do it without a calculator because of decimals..perfect square is easy because they are whole numbers..ex. Square root of 25=5 we do not need a calculator

[@cynthiawilliamsst.johnheal7195]

Thank you so much! I wish you were my teacher back when I was in school. I am studying for a national exam. I have to check to see if I can use a calculator. Have a wonderful day and taking time out of your schedule to answer my questions. You rock!

[@ayskrimajaj3426]

what if I got decimal numbers on the mean, am i gonna round off it or just solve it with decimals?

[@mathhomeworkhelp7575]

Depends on your teacher’s instructions. But usually yes we use it with decimals.

[@argeeonaler1911]

What is the variance? Can you explain it?

[@leasyjackson9794]

Thanks you help me a lot

[@mathhomeworkhelp7575]

[@leahpimentel8515]

What id the mean has decimal numbers? Should we round it off?

[@mathhomeworkhelp7575]

Depends on your instructor. We usually keep one decimal point. For example if the raw data is 9 (whole number) then we keep one decimal point 2.5 for our calculation

[@himanisharma9220]

Ma'am if x&y are given in data set How to used a formula.we need to find y bar x bar or we just calculate like this??

[@mathhomeworkhelp7575]

Are you trying to find the standard deviation?

[@micaelajancisgallardo1086]

teacher what if the median middle part is only one what should i do?

[@mathhomeworkhelp7575]

Then the exact middle number is the median Suppose you have 1,2,3,4,5 then the median is 3 because it is right in the middle.. If you have 1,2,3,4,5,6 then the median would be the average of the two middle number 3+4/2=3.5
