1. 30.5

2. 23

Step-by-step explanation:

1. Find the middle of 30 and 31.

2. 21, 22, 23, 24, 25...now cross of a number from each side at a time until you get to the middle.

You put the numbers from smallest to biggest and cross off one number at a time from each side until you get to the middle.

If at the end you have two numbers left, you find the middle for these two numbers.

1) 30.5

2) 23

3) 50

4) 2

5) 100

Step-by-step explanation:

First of all, order your data from lowest to highest value. Next, if you have an even number of observations (like in question n. 1 and n. 3) you have to add the middle two observations and divide the result by two. If you have an uneven number of observations, your median is simply going to be the number in the middle. Here, I'll show you:

- Question 1 has 2 observations, meaning you have to compute 30+31 = 61. Now you divide 61 by 2:

61/2 = 30.5 and that's your median.

- In question 2 you firstly have to order the data from lowest to highest number. Since it's an uneven number, your median is going to be 23.

- Question 3 has 4 observations, meaning you have to firstly order in ascending order and find the middle 2 numbers, which are 30 and 70. You add them: 30 + 70 = 100.

100/2 = 50 and that's your median.

- In question 4, after you order in ascending order you can clearly see that your median is 2.

- In question 5, after you order in ascending order you can clearly see that your median is 100.
