1) Take average

2) Calculate the log 2 value and the Z value for each.

3) Anything more than +/-1.81, its significant.

Thanks Saifur. Sorry, I was late in replying. But, why the scores towards +/- 3.4 are not significant ? And also, essential to convert the z-scores into Percentages ? If so, how to covert the bulk data z-scores into percentages using the Z-score Table using an Excel sheet ? Thanks in advance, Biswa

I mentioned +/-1.81 based on 95% confidence. You can make your data less confident by increasing the value. Then your data will need more experiments to make it trustworthy.

Calculate average of all data. Calculate log2 for each. Then calculate Z value for each. For more, plz check the following article:http://www.sciencedirect.com/science/article/pii/S1359644613003954
