We have collected much interesting data this week on ourselves and made some equally interesting graphs so that we could talk about using data. Here are some new words we learned.
median - the middle number in a set of data when the data is put in order from least to greatest
mode - the number in a set of data that occurs most often
mean - the average number (add all the number and divide by the number of numbers)
outlier - a number in a set of data that is distant from the other numbers (an outlier may give you unreliable information)
