What can be used to show the difference in variation for two populations that have equivalent measures of center?
I just took the quiz and got three questions wrong and this was wrong also. here are the REAL answers

7. Do it yourself
These are the real answers for connexus students. Have fun with your A =)
is WRONG!!! correct?
wrong is correct 100% correct
WRONG!! Is correct thx man
its correct :)
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.
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.
