Quartiles Today we are learning... What quartiles are and how to calculate it. I will know if I have been successful if... I understand what the quartiles represent. I can find the median. I can find the upper and lower quartiles. The Quartiles Quartiles help us to investigate the spread of the data.

The Quartiles Lower Quartile - Q 25% of the data is below this point. Median - Q 50% of the data is below this point. Upper Quartile - Q 75% of the data is below this point.
