I chose these two videos about mean, median, and mode. These two videos help and show me how to do the math to find the mean. When you need to find the median and there are two numbers left in the middle, you add both of the numbers together and you divide them both by two to get the median. The mode is the number that appears the most. Both of these videos tell you to put all the numbers in order from least to greatest. Then the number that appears the most is the mode. The things that I didn't know or understand about mean, median, and mode, I understand now because the videos helped me.

I chose these two videos about mean, median, and mode. The first video is a rap about mean, median, and mode.I think that the rap is a fun way to remember the mean, median, and mode. The second video is not a rap it is just talking and explaining to you how to do the mean, median, and mode. It takes points from three basketball games and then the numbers get put in order, 4,4,7. The mean is 15 divided by 3, which is 5. The mode is four and the median is four. The mode is the number that appears the most and the median is the middle number.

**Standard Deviation**

media type="custom" key="23022402" In the standard deviation videos, the men explain the importance of standard deviation. He starts with a discussion of normal distribution and how the standard deviation measures the average distance from the mean of data. He then shows you how to calculate standard deviation by hand using the formula. He finally shows you how to calculate the standard deviation using a spreadsheet. To me, this was the most simple explanation of standard deviation.

**Outliers**

media type="custom" key="23035416" These two videos are about outliers. These videos help you examine and find outliers in box plots, histograms, scatter plots, etc.The first video tells you that lower and upper extremes are also know as outliers.The second video gives you a real life problem. Then you have to identify any outliers and you have describe how the outliers affect the mean and standard deviation.

**Quartiles**

media type="custom" key="23063584" These two videos are about quartiles. They tell you that 25% represents the first quartile, 50% represents the second quartile, and 75% represents the third quartile. Those are three different precentile rankings. And quartiles are usually on a line. And the quartiles are split into four parts on the line.

**Data Representations**
media type="custom" key="23075138" media type="custom" key="23075206" These two videos are about data representations. They use histograms, scatter plots, and box plots to represent their data.They tell you the definition of data representations. The second videos is very helpful. It tells you that you need to know about discrete data and continuous data. Discrete data is countable, and continuous data is measurable.
