Dear Members
i am facing problem in calculation of average value in merged columns . Let say i have total 9 data from 3 test replicates. I want to take average of each test replicate and followed by overall average of all data from these average value of individual test replicate average value. I also want to calculate Std.ev of these three mean values.
For more details you can find the origin sheet attached herewith. Please help, i am trying it from past 6 hours but it is not working (i have used the set column value function).

Hi,
Please rearrange your worksheet as below to get the values
*To get col(f) and col(g)*
1. Highlight column A and B, choose menu "Analysis:Mathematics:Reduce Duplicate X Data"
*To get col(h) and col(i)*
1. Highlight col(G).
2. Open Command window if it is not opened yet (menu "Window: Command Window")
2. In the command window, type script as below and press Enter
colstats -d
I also attached the OPJ as below, You can click the green lock on the columns to see how the dialog is set to get the values.

Dear Echo_Chu,
Thanks for your active assistance on query. My question is bit different, plz try with below given update sheet, hope this time i have presented it in more clear way and you will understand it .In this i want separate mean for each three data (till that it is working fine, till column C)but the problem start when i further proceed to take mean from different mean values (column D: it is not coming right).

And at the end i want graph between column E1(X-axis) and D (y-axis)with error column (E).
Looking forward for your assistance.
Thanks |

Hi,
I am a little confused with your project file.
Please note that the mean value in column D is not (90+120+70)/3. It is because if I remove the merged cells in column C, it looks as below
Anyway, I suppose what you want is to remove the duplicated values and calculate the mean for the unique values. If so, you can
1. Remove duplicated rows with menu "Worksheet: Remove/Combine Duplicated Rows"
2. Calculated the statistics from the new column with reduced values (menu "Statistics: Descriptive Statistics: Statistics on Columns")
