When working with statistical software programs, you should do one or two calculations by hand just to make sure the software is working properly. The last thing you want is to have an error happen because you didn’t illuminate the inside of the black box.
A student asked for help with a statistical analysis the other night, and I was happy to help. However, he threw me a curveball when he told me he needed to conduct an ANOVA test using only summary data. That is, all he had was the table of results (from a publication) and not the data. Doing an ANOVA by…
When I was studying medical technology, my professors and mentors emphasized the need to learn to do by hand all of the procedures that automated instruments did. Those instruments, which are veritable robots, can do a complete cell count in a few minutes. Doing a complete cell count by hand takes at least an hour if you’re good and organized……

Unfortunately, he decided to label the “Black Lives Matter” (BLM) movement as a hate group. This is unfortunate because we’re at a point in history where there needs to be a discussion…
Quick, what’s the difference between a gun and a swimming pool? Don’t answer that. It’s a stupid question. Anyone with a grade school education — or even no education — should be able to tell the difference between the two. However, there continues to be this comparison between guns and swimming pools in trying to justify the refusal of any…
