Inconsistent results between the t-test and the overlapping error bars?
Inconsistent results between the t-test and the overlapping error bars?
BE CAREFUL. This may mean that you have made something wrong in the processing,. Further analysis is required. 1) Search for outliers in raw data using a mathematical method. 2) Show the average and standard deviation ranges clear so that the overlapping can be clearly seen (average ± standard deviation). 3) Compare the calculated and critical value in the t-test, if they are close, no statistical difference will be seen between the averages at a confidence level of 10%. Discuss this.

You can use t-tests to check if there is a significant difference between each of your treatments. You should make one t-test for every comparison you make and for every test, state the H0 and the H1.
Test 1: is there a significant difference between treatment 1 and treatment 2? H0: There is no statistical difference in the DV between (your IV1) and (your IV2). H1: there is a significant difference between ...
