Difference Between Standard Deviation And Standard Error Of Measurement
Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Standard Deviation vs Standard Error up vote 2 down vote favorite I am confused about the difference between standard deviation and error. When do I use which? From my lecture: Standard deviation quantifies spread of data about mean Standard error measures spread of all means
Difference Between Standard Deviation And Standard Error Of Estimate
I actually learn this from my physics data analysis lesson. So suppose I have a set of measurements of distance ($D$) verses time ($t$) and I want to compute avg velocity: $t_{avg}$ is calculated as $(t_1 + t_2 + t_3)/3$ (of course I used excel's AVERAGE here). Then avg velocity was $t_{avg}/D$. Then I was asked which measurement #1-10 I think is the closest approximate the the actual velocity. So I was thinking I find the standard error and the one with the lowest is the closest approximate? Is this the reasonable thing to do? I found standard error by STDEV(t_1, t_2, t_3)/SQRT(3). Is this correct? Heres my confusion: STDERR is defined as the spread of all means. I am calculating the spread of all measured data? Not the mean? standard-deviation data-analysis share|cite|improve this question asked Sep 9 '12 at 5:58 Jiew Meng 1,77353364 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote In the context of your example: Does it really make a difference which you use? If standard deviation is 's'. The standard error is just s/SQRT(n). This is a linear transf
the toolbar at the top. 2. A menu will appear that says “Paste Function”. Select “Stastical” from the left hand side of difference between standard deviation and variance the menu, if necessary. Scroll down on the right hand side of the menu
How To Calculate Standard Error In Excel
and select “STDEV”; then click “OK”. 3. Click on the picture of the spreadsheet, and highlight the numbers you averaged standard error vs standard deviation earlier, just as you did when taking the average. Hit enter, and “OK” to calculate the standard deviation. 4. With the cursor still on the same cell, now click in the formula bar at the http://math.stackexchange.com/questions/193045/standard-deviation-vs-standard-error top of the spreadsheet (the white box next to the “=” sign) to put the cursor in that bar so you can edit the formula. 5. Put a “(“ in front of STDEV and a “)” at the end of the formula. Add a “/” sign to indicated you are dividing this standard deviation. Put 2 sets of parentheses “(())” after the division symbol. Put the cursor in the http://mtweb.mtsu.edu/ajetton/Graphing_Guides/Excel_Guide_Std_Error.htm middle of the inner set of parentheses. 6. Now click on the fx symbol again. Choose “Statistical” on the left hand menu, and then “COUNT” on the right hand menu. 7. Click on the spreadsheet picture in the pop-up box, and then highlight the list of numbers you averaged. Hit enter and “OK” as before. 8. Move the cursor to be between the 2 sets of parentheses, and type “SQRT”. Hit enter. The standard error of the mean should now show in the cell. Your formula in the formula bar should look something like this, “=(STDEV(A1:A2))/(SQRT(COUNT(A1:A2)))”. (This formula would calculate the standard error of the mean for numbers in cells A1 to A2.) NOTE: We have calculated standard error of the mean by dividing the standard deviation of the mean by the square root of n. Given the formula that Excel uses for calculation of standard deviation of the mean, this gives the standard error of the mean after adjusting for a small sample size. This is usually the case in physiology experiments. The formula would be different with a very large sample size. I do not know why Excel still does not include a formula for calculating the standard error of the mean.
