- What was the median number of A’s earned ?

- What was the high number of A’s earned by students?

**Analyzing Data-Looking at Center Spread and Shape** In this video you will learn about center spread and shape. Measure of center includes mean, median, and mode. Spread includes the range of a data set, and IQR. Finally shape includes looking for outliers,clusters,and gaps in the data.

**Integers** In this animated Middle School Math video you will learn the basics of integers. Integers are whole numbers that are not fractions,decimals, or percents.

**Percentage Change **What percent change is 73 to 86? In this video you will learn how to solve these percent change problems. The video covers both percent increase and percent decrease.

**Converting Decimals to Fractions:** Learn how to convert a decimal to a fraction using these three easy steps,create a fraction,the numerator will become the number to the right of the decimal point, and the denominator becomes the value of the last number. Finally, simply the fraction.

**Dividing with Decimals: **Learn how to divide with decimals. If the divisor is not a whole number, move the decimal point to right to make it a whole number, and move the decimal point of the dividend the same number of places.

Follow these simple rules for adding and subtracting integers.

If the signs are the same, add the two numbers and keep the sign of the two numbers.

If the signs are different, subtract the two numbers and keep the sign of the larger number.

If the problem is subtraction, change the subtraction to addition, and change the sign of the number after the subtraction sign, and then follow the addition rules.

**Adding and Subtracting Integers using Counters: **In this video counters are used to help people visualize the rules of addition and subtraction of integers. This video will really help if you struggle with adding and subtracting positive and negative numbers.
