Loving it so far. Wish the search for documents in their library was easier to find, but other than that, I've been very happy with ease and quality.

Easy to use, a little misleading on the web site "try for free" and then it wants to charge me to save / print, but live chat was quick and the chat agent (Anne) was awesome and provided me a 7 day free trial so I can see if this will be worth the subscription. Hats off to the chat agent, awesome customer service, GIVE her a RAISE! LOL

Other than being billed initially for a 30 days trial, I contacted Customer Service right away and they credited me back the $144 first year right away. Otherwise, I am liking the service so far. Just learning how to use it.

How do you indicate significance in a letter?
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 use letters to show significant differences?
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 show significant difference?
Usually, statistical significance is determined by calculating the probability of error (p value) by the t ratio. The difference between two groups (such as an experiment vs. control group) is judged to be statistically significant when p = 0.05 or less.

Which letter is used to represent the significance value?
A hypothesis test or test of statistical significance typically has a level of significance attached to it. This level of significance is a number that is typically denoted with the Greek letter alpha.
What is significance level alpha?
The significance level, also denoted as alpha or, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference.
What is an example of statistical significance?
Statistical significance is most practically used in statistical hypothesis testing. For example, you want to know whether changing the color of a button on your website from red to green will result in more people clicking on it. P-value refers to the probability value of observing an effect from a sample.
Why is an alpha level of .05 commonly used?
Why is an alpha level of. 05 commonly used? Seeing as the alpha level is the probability of making a Type I error, it seems to make sense that we make this area as tiny as possible. The smaller the alpha level, the smaller the area where you would reject the null hypothesis.
