What can be used to show the difference in variation for two populations that have equivalent measures of center?
You could use Interquartile Range and show this with a boxplot for each of the.. That is the difference between the 1st and 3rd quartile.
C. Median i took the quiz
I just took the quiz and got three questions wrong and this was wrong also. here are the REAL answers
1. C
2. D
3. A
4. A
5. C
6. A
7. Do it yourself
These are the real answers for connexus students. Have fun with your A =)
is WRONG!!! correct?
no he is not the first answer is B but that's all I know of.
wrong is correct 100% correct
WRONG!! Is correct thx man
its correct :)
To show the difference in variation for two populations that have equivalent measures of center, you can use the standard deviation or the interquartile range.
1. Standard Deviation:
- Calculate the standard deviation of each population.
- The standard deviation measures how spread out the data points are from the mean.
- If the standard deviation is higher for one population compared to the other, it indicates a greater variation in that population.
2. Interquartile Range (IQR):
- Calculate the IQR for each population.
- The IQR represents the range between the first quartile (Q1) and the third quartile (Q3) of the dataset.
- It measures the spread of the middle 50% of the data and is less sensitive to extreme values than the standard deviation.
- If the IQR is larger for one population while both populations have equivalent measures of center, it suggests a greater variation in that population.
By comparing the standard deviation or the interquartile range of both populations, you can determine which population has a greater difference in variation, even if their measures of center (such as mean or median) are equivalent.
