For example, the items you wear: hat, shirt, jacket, pants, and so on. I'm sure you could come up with at least a hundred. This is known as a set.You know what the equal symbol means and looks like. If a = b, then a and b are equal, (8 = 8). To learn about ordering real numbers, think about it this way. If a real number b is greater than a real number a, their relationship would look like this: −2 > −5 since −2 is to the right of −5 on the number line. Here's a quick preview of the steps we're about to follow: Step 1: Find the mean. Step 2: For each data point, find the square of its distance to the mean. Step 3: Sum the values from Step 2.
