When to use the z-test versus t-test

How do I know when to use the t-test instead of the z-test? Just about every statistics student I've ever tutored has asked me this question at some point. When I first started tutoring I'd explain that it depends on the problem, and start rambling on about the central limit t...

When a correlation is calculated, the resulting coefficient can be a positive number or a negative number. Positive correlations are a direct relationship meaning the two quantitative variables move the same direction. Negative correlations are an inverse relationship meaning the two quantitative variables move in opposite directions. In either case, the correlation coefficient should be a decimal number between -1 and +1. Graphic could be used in a PowerPoint as an illustration.

In this activity AP Statistics students will practice selecting the correct method of inference from a drop down menu, and then calculating portions of each inference method. Students will be conducting a confidence interval for proportions, a hypothesis test for a mean and for a mean difference, a hypothesis test for a difference in proportions and more! In this activity students will be filling out their statistic, point estimate, margin of error, interval, p-value and test-statistic.
In this activity, students will practice constructing confidence intervals for proportions. Students will not be checking conditions, although they may! Every questions tells them that all conditions have been met. The purpose is to get students practicing with their calculator to come up with each interval. Includes a total of 7 questions. This is great practice for the AP Statistics test. I use these activities as quick check for understandings and also as exit tickets, homework or warm ups.
In this activity for AP Stats, students will practice identifying the mean and standard deviation of sampling distributions. The activity provides immediate feedback! As students type in the correct answer, a piece of the puzzle dissapears and reveals a funny meme.
We’ve all been there. Someone says something that gets under our skin and then it’s game over. Before you know it, you’re reacting negatively and following the old subconscious programming. But what if you could learn to operate from a more positive, proactive programming? Today we share with you exactly where to begin so that you don’t absorb other people’s poor belief systems any longer.
