Example 1
The school district designed a district-wide end-of-course exam for math. Last year, 330 students took the exam. A random sample of exam scores, shown below, were chosen to represent the entire group.

85, 92, 65, 85, 65, 85, 77, 92, 92, 66, 77, 92, 77, 77, 65, 85

What is the median?

What is the mean?

What is the mode?

What is the range?

Step-by-step explanation:

Mode=77&92&85 (mode is most common number)

Mean= 85+92+65+85+65+85+77+92+92+66+77+92+77+77+65+85=1277

1277/16=79.8 = 80 (Mean is add all numbers and divide how many there is.)

Range=92-65=27 (Range is highest number take away lowest number)

Median: 65,65,65,66,77,77,77,77,85,85,85,85,92,92,92,92

so median is 81 (put numbers in order and find the middle number. if order is even add two numbers in middle and divide by two. If order is odd, find ONE number.)
