What are the five steps to determining statistical significance?
Stating the research and null hypotheses and selecting (setting) alpha. Selecting the sampling distribution and specifying the test statistic. Computing the test statistic. Making a decision and interpreting the results.
How do you determine significance level?
To find the significance level, subtract the number shown from one. For example, a value of “. 01” means that there is a 99\% (1-. 01=.
How do you assess the statistical significance of an insight?
Start by looking at the left side of your degrees of freedom and find your variance. Then, go upward to see the p-values. Compare the p-value to the significance level or rather, the alpha. Remember that a p-value less than 0.05 is considered statistically significant.
How do you use denote statistical significance?
If we use upper-case letters to indicate results significant at the 0.05 level and lower-case to indicate results significant at the 0.001 level we get: a>b, A>D, a>f, a>g, c>d and c>f. (Often commercial studies use upper-case for significant at the 0.05 level and lower case for significant at the 0.10 level.)

How do you determine statistical significance on a graph?
6 Ways to Visualize Statistical Significance
- Confidence Interval Error Bars. Confidence intervals are one type of error bar that can be placed on graphs to show sampling error.
- Standard Error Error Bars. Another type of error bar uses the standard error.
- Shaded Graphs.
- Asterisks.
