NOTE: For a straight line: the rate of change of y with respect to x is the same as the gradient of the line. Formally, the p-value is the probability that the test statistic will produce values at least as extreme as the value it produced for your sample. It is crucial to remember that this probability is calculated under the assumption that the null hypothesis H 0 is true! For example, in a two-tailed t test, the null hypothesis is that the difference between two groups is zero. Example: Null and alternative hypothesisYou want to know whether there is a difference in longevity between two groups of mice fed on different diets, diet A and diet B. You can statistically test the difference between these two diets using a two-tailed t test. But sometimes, you may struggle to find a perfect slide layout for the content you're sharing. Of course, you can move objects around the slide to make it look different. Wouldn't it be useful to get a bit of help?

One of my favorite PowerPoint presentation tips is to complement your major points with a bit of animation. Using animation can bring a key point onto your slide with style! It is the alternative hypothesis that determines what "extreme" actually means, so the p-value depends on the alternative hypothesis that you state: left-tailed, right-tailed, or two-tailed. In the formulas below, S stands for a test statistic, x for the value it produced for a given sample, and Pr(event | H 0) is the probability of an event, calculated under the assumption that H 0 is true:

Again, Envato Elements is the perfect subscription if you build presentations. It's a one-stop shop that you can use to fill content. 11. Reduce Your Content Once slides are ready, practice one slide at a time aloud until you feel like you know it and like the flow of speech. Be willing to change anything that does not feel in flow. At the end of learning all your slides, practice the whole talk. P values are often interpreted as your risk of rejecting the null hypothesis of your test when the null hypothesis is actually true.
