# T-Test

Hi,

I have one excel sheet containing two attributes one is score(Numeric) and other is category(M or F).I would like to Test whether there is any significant difference in scores between two categories using T-test.I used excel example source and T-Test operator.But it is not working.Any body can provide the names of operators to get the result.

Thanks

68MavenIn T-Test operator,we can adjust only significance level(alpha).Is there any way to mention independent sample t-test(equality of two population means)or Paired t-test(dependent t-test)or one sample t-test.

Thanks

IF(length of both performance-vector is equal)

dependent t-test for paired samples

ELSE

independent t-test with assumption of equal variance

END

one-sample-test is not implemented.

On a side note, I do not know how to transform an exampleset into an performance-vector, but that is another story..
