Answer:
Mean: 4, Median: 4, Mode: 4, Range: 5
Explanation:
First Put the numbers in order from least to greatest:
2, 2.5, 3.1, 3.7, 4.3, 4.3, 5.1, 7
MEAN: The mean of a group of numbers is the the average so we'll add up all the numbers then divide them by the amount of numbers total. In this case: the um of all the numbers is 32. We are going to now dived 32 by 8, because there are 8 numbers. Using my multiplication facts, I know that 8*4 equals 32, therefore, 32/8 equals 4. So your mean is 4
MEDIAN: Your median is the middle number. This is why it was helpful to put the numbers in alphabetical order. In this one, you will cross off numbers from each end to find the one in the middle. Here is where it would be good to have a piece of paper and a pencil to cross out the numbers as you go. If you don't have paper, you can use your fingers, which is what I did. Take your finger and put it in front of the end numbers and from there keep going until you have a final middle number. In this case, there are 2 numbers in the middle, so you take the average of those 2 numbers. The two numbers in this problem are 3.7 and 4.3. You ad those together, and you get 8, now you divide 8 by 2 because you have 2 numbers. 8/2 is 4. So your median is 4.
MODE: is the easiest. It's simply the number that appears the most times in the sequence of numbers. so the mode here is 4.3.
RANGE: Range is the difference between the number with the highest value and the number with the lowest value. The highest value is 7 and the lowest is 2. 7-2 equals 5. So your range is 5
