A data set includes the following SAT scores: 340, 560, 480, 680, 700. Suppose an additional score of 700 is inserted in the data. How will the median be affected?

Answer 1

Answer:

Step-by-step explanation:

Let's first arrange it in ascending order :

340, 480, 560, 680, 700

560 is clearly the median.

Now add an additional score of 700 to the data :

340, 480, 560, 680, 700 ,700

560, 680 is separating both halves but is not the median

Median = (560+680)/2

             = 1240 / 2

Median  = 620
