Answer:
Step-by-step explanation:
First step to finding the mean, is to add all of the numbers up.
5.1 + 3.7 + 3.1 + 4.3 + 7.2 + 4.3 +2.5 = 30.2
The next step is to divide the total against the amount of numbers in the sequence. Since there are 7 numbers in this sequence, you will divide 30.2 by 7.
30.2 / 7 = 4.3 (rounded to the nearest tenth)
The mean of the data set is 4.3
To find the mode, you will look for the number of the set that appears most frequently. I suggest putting the numbers in order of least to greatest, as this keeps them sorted and organized.
2.5, 3.1, 3.7, 4.3, 4.3, 5.1, and 7.2
Looking at these numbers, you can see that 4.3 pops up twice in the data set. This will be the mode, because it is the number that appears most frequently.
To find the range, you take the greatest number in the data set, and subtract it by the smallest.
7.2 - 2.5 = 4.7
That means that 4.7 is the range of the data set.
