Study Tips:

Have a game plan

It’s wise to make a study plan for the test in advance. It’s even wiser to get an idea of the test’s time limit and to estimate how much time you can use for each problem. A general rule of thumb is to limit true or false questions to 30 seconds, multiple choice questions to a minute, short response questions to 2 to 4 minutes, and long response questions to eight to ten minutes. Adjust these guidelines depending on the test, but be sure you have around half of the time left for review. 

Time yourself

Speed + accuracy = good math grades. After you create your timed plan to ace that stats test, time yourself so you can execute it. First, use a stopwatch to measure how much time you take on a certain type of problem. If you get the problem’s concept, practice those problems with a time limit slightly lower than how long you took for the stopwatch-timed problem for each question. If you don’t get the concept, it’s time to hit the books. Speed and accuracy come with understanding the material, which is very important in statistics.

Understand the material inside and out

Memorization was the key to math. In statistics, not only do you have to learn how the formulae work, you have to understand why they work. In addition, you’ll have to memorize vocabulary, concepts, etc. That probably comes from stats being a horrid lovechild of math, English, and science. Usually, test questions will pop up asking you to prove something in statistical terms. To ace these, memorize the exact definitions. Statistical terms can overlap with everyday words, and it’s best to not get them confused. For understanding concepts, learn them however you can. Watch videos, read guides, do practice problems, make mind maps, explain it to a group of toys like they’re five-year-olds, etc. The feeling of getting a concept is a rare, blissful nirvana. That knowledge can be used to help other struggling students.
