# New Biology A Level - Statistical tests?

Announcements
#1
Hey everyone,

I do the new AQA A level biology syllabus, and I was just wondering if we actually need to know how to do all the tests mentioned on our syllabus (standard error + 95% confidence intervals, chi-squared, spearman's rank and t-test) or do we just need to know when to apply them??

Any help will be appreciated!!!

I'm confused because in the first table shown (link), they expect us to know how to select and use the test, but on the next page, it says that :

"In written examinations, students might be asked to perform simple calculations such as finding a mean value. Students will not be asked to perform a calculation using a statistical test (or to calculate the standard deviation of a mean)."

You're expected to know how it works and when it's used, but in the new spec you don't have to know how to actually calculate the statistical test
