Find the mean,median, mode, and range.
10,8,12,6,5,4,10.
This is what I got: Mode:10 Median:8 Mean: 7.9 Range: 8
However, none of these are the answer choices. Am I doing something wrong??
4, 5, 6, 8, 10, 10, 12
I get the same answers. Are you sure your original numbers are correct?
I'm pretty sure. Here are the answer choices:
A) Mean=11.86 Median= 12 Mode= 8 Range=14
B) Mean= 12 Median= 11.86 Mode= 14 Range= 8
C) Mean= 12 Median= 11.86 Mode=8 Range= 14
D) Mean 11.86 Median= 12 Mode=14 Range= 8
Ask your teacher. There must be a mistake in that question.
To find the mean, median, mode, and range in a set of numbers, follow these steps:
1. Mean: Add all the numbers together, then divide the sum by the total count of numbers.
Let's calculate it for the given set:
10 + 8 + 12 + 6 + 5 + 4 + 10 = 55
55 ÷ 7 = 7.857 (rounded to 3 decimal places)
The mean (average) for the set is approximately 7.857.
2. Median: Arrange the numbers in ascending order, then find the middle value. If there are two middle values, find the average of those values.
Arranging the set in ascending order: 4, 5, 6, 8, 10, 10, 12
There are two middle values: 6 and 8. To find the median, calculate the average of these two numbers.
(6 + 8) ÷ 2 = 7
The median for the set is 7.
3. Mode: Determine the number(s) that appear most frequently.
In this set, the number 10 appears twice, which is more than any other number.
The mode for the set is 10.
4. Range: Calculate the difference between the largest and smallest values in the set.
The largest value is 12, and the smallest is 4.
12 - 4 = 8
The range for the set is 8.
Based on these calculations, the mode: 10, median: 7, mean: 7.857, and range: 8.
If your answer choices do not match, please double-check that you have followed these steps correctly and compare your results to the given options.
