Good Evening All, I have been able to successfully calculate the 3 Year Standard Deviation for the S&P 500 using monthly data. The figure I obtain coincides with outside data vendors and I assume is correct. When I attempt to calculate the 3 Year Standard Deviation on the same Index, over the...

Hello! I have trouble finding the mean and probabilty when only the standard deviation is given. I have the correct answer, look below questions. I think NORM.S.DIST might be the correct formula, but I cant figure out HOW to use this to get the solution. QUESTION 1) A Top-load washers at a...

Good evening, I am creating a monte-carlo simulation using NORM.INV distribution based on a mean and standard deviation. However, the distribution of the data that these numbers are based on is skewed; which doesn't get reflected, as only using mean/sd produces a symmetrical distribution. Is...

Hello, I am working on a project and told to remove all outliers by using the ? +- 3? approach. I am wondering how i should go about this? do i need to calculate the mean and all quartiles to remove the outliers or is there a single excel function that can remove the data outside 3 standard...

I am trying to find the standard deviation for data presented in different ranges and I am currently using the following equation: =+STDEV.S(IF((e7a1!A12:A1010>=Primary!K$5)*e7a1!A12:A1010<=Primary!K$6);INDEX(Table1;0;MATCH($D19;Table1[#Headers];0));)) The reason for the formatting is that its...

I'm trying to calculate standard deviation based on multiple criteria. I've used suggestions show on this site and on Google, but it keeps returning the SD of the entire list, not just those that match. Here's the formula I'm using: =STDEV.S(IF($C$2:$C$10=$L2,IF($E$2:$E$10=$M2,$H$2:$H$10)))...

I can calculate the standard deviation when the cell condition is above or equal to 70 using this formula. <code style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas...

Hi all, Looking for some help with a standard deviation formula, integrated with an if statement. I'm using 'AVERAGEIF' and have read many articles about how to achieve something similar for the standard deviation using an array formula, i.e.; {=STDEV(IF(B3:B8="TEST1",D3:D8,""))} This appears...

I am trying to highlight cells which are between two numbers but not between two other numbers in order to highlight data values used to create a histogram using standard deviation. I understand that I would use conditional formatting but I'm not sure how to set up the equations. Here is...

I have 3 years of data in 6 minute averages that I would like to get the standard deviation by hour and add it to the hourly average. I created a standard deviation in the "Values" section, but this field does not show up in the calculation field list. Is there a way to create a calculation of...

Hi guys, I have a column of data (column H), and I'm trying to take the average & standard deviation of just the middle 80%. I can't seem to figure out how to do this. Thank you all for your time!

Can anyone help me with how to break a ranking tie using standard deviation? 10 people rank their choices from 1-10 (10 being best), so I started with a plain basic rank based on the sum of all 10 people's choices. Highest overall number represents the groups most favorite choice. I would like...

I am sure you can tell by the title this is going to be fun! I have an array of random number of card players getting a random (but equal) number of cards. The cards are all numbered based on "power". So card 50 is weaker than card 49. I have the random number generator all set up to...
