We defined mode, median, mean, lower quartile, upper quartile, and interquartile range. Marcos now has a list of the definitions on his board. Given a list of data, he worked through 3 exercises where he had to find all of the above for the data. Mode: data that occurs most, Median: data in the middle, mean: average, lower quartile: the median of the lower half of data, upper quartile: the median of the upper half of data, interquartile range: the difference between the upper and lower quartile. Marcos was focused!
