# How To Solve Statistics Problems What Should A Covering Letter Always Include SAT questions are always tricky and knowing how to handle their version of these types of questions will serve you well as you go through your test.

This will be your complete guide to SAT means, medians, and modes—what they mean, how you'll see them on the test, and how to solve even the most complicated of SAT statistics questions.

Before we look at how to solve these kinds of problems, let us define our terms: A mean is the statistical average of a group of numbers, found by adding up the sum of the numbers and then dividing by the amount of numbers in the group.

What is the average test score for the class if five students received scores of: 92, 81, 45, 95, and 68?

Having a 1:2 probability for heads means that you will get a heads half of the time.

This is why coins are used to make decisions, like who goes first in a football game–both teams have a 50% chance of going first and that is fair.

You know that your mother makes turkey on 5 days, and beef on 2. Even though there are two puppies, we are only thinking about one right now. That makes two possible events, with one outcome; so there is a 1:2 chance that one puppy is a girl. So using the steps for solving a joint probability there is 1:4 change that both puppies are girls.

A) \$m 6\$ B) \$m 7\$ C) m 14\$ D) m 21\$ There are a lot of variables in this equation, but don't let them confuse you.

We already know that the average of two numbers is the sum of those two numbers divided by 2.

If you are given an even number of terms in the set, then you must take the mean (average) of both middle numbers. First, arrange the numbers in order from least to greatest.

3, 4, 7, 10, 12, 15 We have an even number of terms in our set, so we must take the average of the two middle terms.   A probability tells you how likely something is to occur.
