This is the concern you express in your question. You also need to consider what you would do if the first test was significant and the second not, which happens with probability α(1−α)α(1−α) or β(1−β)β(1−β) depending on which hypothesis is correct. Share Cite ...
What is an example of a hypothesis? What does it mean for a hypothesis to be falsifiable? What does hypothesis mean? What is an example of a null hypothesis? What is a null hypothesis? What are Type I (or alpha) and Type II (or beta) errors in statistical hypothesis testing? Illustrat...

The mean is a useful measure when the data is normally distributed and the outliers do not significantly affect the overall pattern of the data. Regression Regression Analysis is a statistical method used to model the relationship between two or more variables. It is a powerful tool for predict...
The t-test is a test used for hypothesis testing in statistics. Calculating a t-test requires the difference between the mean values from each data set, the standard deviation of each group, and the number of data values. T-tests can be dependent or independent. ...
Parameters in groups were expressed as median and quartiles or as mean and standard deviation. The statistical significance between different groups was calculated with one-way analysis of variance (ANOVA), alternatively using the non-parametrical U Mann–Whitney* test (for two groups) or Kruskal–...
