Question Skewed Distribution

I need help with the skewness. If you can so kindly explain and show an example of how they are skewed (e.g., negatively or positively skewed?) I’m so lost for this part. I read the book, but the book only gives a definition - no examples or demonstrations.

Here is what I know about skewness: If the tail is to the left, it is negatively skewed. If the tail is to the right, then it is positively skewed. That is pretty much where my knowledge is at on it. The book didn't go further than that. I know what a negatively or positively skewed graph looks like. However, there are no pictures, illustrations, examples, or demonstrations for me to see how to do / figure out the skewness. If you can so kindly explain how I can find out if they are skewed or not, then I'd be soo grateful. I need to have a full understanding of this so I can always remember this concept.

Are they skewed, negatively or positively?

Simple rule: compare median and mean. The distribution is skewed on the side of the mean.
