  9. Important Every section represents 25% of the data Min to Q1=25% Q1-Median=25% Median-Q3=25% Q3-Max=25%

  10. Step 1: Find Median The middle-most value of a data set; 50% of the data is less than this value, and 50% is greater than it Example:

  11. Step 2: Find First Quartile The value that identifies the lower 25% of the data; the median of the lower half of the data set; written as Example:

  12. Step 3: Find Third Quartile Value that identifies the upper 25% of the data; the median of the upper half of the data set; 75% of all data is less than this value; written as Example:
