question #10\nwhat is the median score achieved by a student who received the following scores on 10 math quizzes?\n68 66 70 62 71 58 81 82 63 79\nsaved 70\n68\n69\n71
Answer
Explanation:
Step1: Sort the scores
$58,62,63,66,68,70,71,79,81,82$
Step2: Find the middle - two numbers
Since there are $n = 10$ (an even number of data points), the middle - two numbers are the $\frac{n}{2}=5$th and $\frac{n}{2}+1 = 6$th ordered values. The 5th value is $68$ and the 6th value is $70$.
Step3: Calculate the median
Median=$\frac{68 + 70}{2}=\frac{138}{2}=69$
Answer:
69
