Everyone learns differently. I can recall my undergrad days and how jealous I was of students who got A’s and never read the text book. I tried to be like them and failed miserably. I need to read the text book as part of my mojo. Reading and translating the text into my own words helps me KNOW it. And when I KNOW something, watch out. Now in terms of hypothesis testing and confident intervals, some people benefit from graphing out the z values on the bell-curve. If you draw out the normal distribution curve and plot your Z values -it does help. Because you can recognize why we divide out alpha by 2 for confidence intervals. Or why we use a particular Z value for a two-sided hypothesis test versus one-sided. Try it!
