The one that occurs the most number of times is the mode. I will make tally marks on my data sheet indicating how many times each number occurs. If they all occur the same number of times, we say there is no mode. It is very possible to have no mode. It is also possible to have two modes.
Lets take a look at our new data.
The number in the middle when the data are listed from least to greatest. The number that occurs most often. Now, we are going work together to find the median and mode of these lists of numbers on the page. We don't have an even set of numbers. I will stop after each one to check for understanding.
