Of course, I can help you with finding the mean, median, mode, and range of a set of numbers. Let's begin!
To find the mean:
1. Add up all the numbers in the set.
-12 + (-9) + (-14) + (-39) + (-49) + (-49) + (-18) + (-43) = -233
2. Divide the sum by the total number of values in the set. In this case, there are 8 numbers.
-233 ÷ 8 = -29.125
Therefore, the mean of the given numbers is -29.125.
To find the median:
1. Start by arranging the numbers in order, either from smallest to largest or vice versa.
-49, -49, -43, -39, -18, -14, -12, -9
2. Since there is an even number of values in this set, we take the average of the two middle numbers.
(-39 + -18) ÷ 2 = -28.5
So, the median of the given numbers is -28.5.
To find the mode:
1. The mode is the number(s) that appear most frequently in the set.
In this case, the numbers -49 appear twice, making -49 the mode.
Hence, the mode of the given numbers is -49.
To find the range:
1. Calculate the difference between the largest and smallest numbers in the set.
Range = Largest Number - Smallest Number
-9 - (-49) = 40
So, the range of the given numbers is 40.
Thus, the mean is -29.125, the median is -28.5, the mode is -49, and the range is 40.
