1.What is the mode of the data? Explain.

The mode of a data set is the value that appears most frequently. Imagine you're at a party, and everyone is standing in a line based on their height. The mode would be like the tallest group of people who share the same height—this is the height that occurs the most! In practice, a data set can have one mode (unimodal), more than one mode (bimodal or multimodal), or no mode at all if all values occur with the same frequency. To find the mode, simply tally up how many times each value repeats and identify which one has the highest count. If you have numbers like 2, 4, 4, 7, 9, the mode is 4 because it pops up twice, while the others appear less frequently. It's a handy way of summarizing data when you're interested in the most common item!
