Hello,

I have the following data that is from two different places X and Y where the results are from two criteria High and Low

High    Low

34           25

55           45

65           65

85            75

95            75

and so on.

Consider this is for the Place X and likewise I have values from the Place Y. Can i use T test to compare the values and to find which is best compared to the two places?

Thanks

T-test determines if the means of the two places are statistically different. It does not determine "which is best". You, the data analyst, have to have some criterion for what "best" means.

What happens if you find a statistically significant difference, but the difference is only 2 units? Is that a practical difference?
