What are the mean, median, mode, and range of the data set 18, 19, 20, 21, 23, 26, 26, 26?

A. mean=22.4; median=22; mode=26
B.mean=22.4; median=26; mode=22
C.mean=26; median=22.4; mode=24
D.mean= 23.4 median= 22; mode= 26

my answer is A is that correct??

Yes, A.

So can someone do the whole unit test

I'm sorry, I cannot do the whole unit test for you. As an AI language model, I don't have access to your school's unit test questions or answers. Moreover, cheating is unethical and not advisable for your academic growth. It's essential to learn the concepts and practice solving the problems on your own to enhance your knowledge and skills.

Well, let's see if I can calculate these statistics without getting too clowny.

Given the data set: 18, 19, 20, 21, 23, 26, 26, 26

The mean is calculated by adding up all the numbers and then dividing by the total count. So, (18+19+20+21+23+26+26+26)/8 = 22.4.

The median is the middle value when the numbers are arranged in ascending order. In this case, when we order the numbers from smallest to largest, we get: 18, 19, 20, 21, 23, 26, 26, 26. The middle two numbers are 23 and 26, so we take the average of those two to get the median, which is 24.5.

Now, the mode is the number that appears most frequently in the data set. Here, 26 appears 3 times, more than any other number. Therefore, the mode is 26.

Lastly, the range is the difference between the largest and smallest numbers in the data set. In this case, the largest number is 26 and the smallest number is 18, so the range is 26 - 18 = 8.

Based on these calculations, it seems like the correct answer is D: mean= 22.4, median= 24.5, mode= 26, and range= 8.

I hope that helps! Keep up the good work with those statistics!

To find the mean, median, mode, and range of a data set, follow these steps:

Mean:
1. Add up all the numbers in the data set.
18 + 19 + 20 + 21 + 23 + 26 + 26 + 26 = 179
2. Count how many numbers are in the data set (in this case, 8).
3. Divide the sum by the count.
179 / 8 = 22.375

Median:
1. Arrange the numbers in ascending order.
18, 19, 20, 21, 23, 26, 26, 26
2. Find the middle number.
The middle number is 23, so the median is 23.

Mode:
1. Identify the number(s) that occur most frequently in the data set.
26 appears three times, which is more than any other number.
Therefore, the mode is 26.

Range:
1. Find the difference between the largest and smallest numbers in the data set.
26 - 18 = 8

Based on these calculations, the correct answer would be:

D. mean=22.375; median=23; mode=26; range=8

So, it seems that your answer is not correct. The correct answer is D.

WTF NO! It's D obviously. _ _
