I conducted an experiment of 48 participants, with two versions (A&B) and two dependent variables, DV(1)-taste, DV(2)-cost.

Please further explain the results below in a mathematical standpoint. The results of the two tail P values, the confidence intervals, the T values, how DV(1) is not quite statistically significant, and how DV(2) is statistically significant. Please also help me understand what you can conclude from the results, and the hypothesis you can make.

-Also wondering why the df changed from (48) to (46) in the results?

DV(1) Taste: Difference = 0.7500, t(48) = 1.6874, p = .0983; therefore the difference of DV1 between A and B is not quite statistically significant

DV(2) Cost:Difference = 1.3300, t(48) = 3.7305, p = .0005; therefore, the difference of DV2 between A and B is statistically significant

dv(1):taste

Unpaired t test results P value and statistical significance: The two-tailed P value equals 0.0983 By conventional criteria, this difference is considered to be not quite statistically significant. Confidence interval: The mean of Version A minus Version B equals 0.7500 95% confidence interval of this difference: From -0.1447 to 1.6447 Intermediate values used in calculations: t = 1.6874 df = 46 standard error of difference = 0.444 Learn more: GraphPad's web site includes portions of the manual for GraphPad Prism that can help you learn statistics.
