ANSWER:
Step 1 of 6
The sample median is a measure of central tendency that divides the data into two equal parts, half below the median and half above.
We can also divide data into more than two parts. When an ordered set of data is divided into four equal parts, the division points are called quartiles. The first or lower quartile, , is a value that has approximately 25% of the observations below it and approximately 75% of the observations above. The second quartile is exactly equal to the median, and has approximately 50% of the observations below its value.The third or upper quartile, , has approximately 75% of the observations below its value.
