### Example Question #91 : How To Find Median

What effect occurs on the median of a set if the lowest number of the set is decreased?

**Possible Answers:**

Increases

No effect

Decreases

Cannot be determined

**Correct answer:**

No effect

Since the median is only the middle number of the set and is a countable number, changing the value of the lowest number to an even lower number has no effect on the median. The middle number will remain the same so that means the median remains the same.

### Example Question #92 : How To Find Median

Find the median of the following data set:

**Possible Answers:**

**Correct answer:**

Find the median of the following data set:

First, let's reorder our data set:

Next, identify the median by choosing the middle value

So, our answer is 45

### Example Question #92 : How To Find Median

Use the following data set to answer the question.

Find the median of the data set.

**Possible Answers:**

**Correct answer:**

To find the median of a data set, we will first arrange the numbers in ascending order. Ascending order means from smallest to largest. Once we arrange them in ascending order, we will locate the number that is in the middle or center of the set.

So, given the set

we will first arrange them in ascending order. We get

Now, we will locate the number in the middle or center of the set. We can see that is in the center.

Therefore, the median of the data set is .
