How do you find the mean, median and mode of -500, 350, 475, -300, -500, 450, 425, -400?

Mean#=0#. Median#= -400#. Mode#= -500#.

Mean is equal to the total number of terms divided by the total number of terms. Mean#= (-500+350+475-300-500+450+425-400)/8# Mean#=0/8=0# Median#= (n^(th) term +(n+1)^(th) term)/2# Median#=(-300-500)/2=-800/2=-400# The term that appears the most frequently is called the mode, and in this instance, it is -500. I hope it was useful. -Shantanu Dash

undefined To find the mean, median, and mode of the data set {-500, 350, 475, -300, -500, 450, 425, -400}, you can follow these steps:

1. Mean: Add all the numbers together and divide by the total number of values.
2. Median: Arrange the numbers in ascending order and find the middle value. If there are two middle values, find their average.
3. Mode: Determine the number that appears most frequently in the data set.

For this data set:
- Mean: (-500 + 350 + 475 - 300 - 500 + 450 + 425 - 400) / 8 = 200
- Median: Arrange the data in ascending order: -500, -500, -400, -300, 350, 425, 450, 475. The median is the average of the two middle values, which are -400 and -300: (-400 - 300) / 2 = -350.
- Mode: -500 appears twice, which is more frequent than any other number in the data set. Therefore, the mode is -500.
