correlation is drawn from all data points. if you look at the r^2 value and it's below 0.99 for example (should be higher in non research work (and in much research work) it indicates that 1 of your points may be an outlier. If you input all datapoints into excel, you may be able to see the point that's throwing it off. There are also statistical tests you can do to spot an outlier.
In other words, correlation is not independent of an outlier. it will make the r^2 value worse. If the outlier is taken out, then the correlation could be deemed independent but only because you manipulated it and had taken the outlier out

Can there be 2 outliers in a set of data?
There is no limit to the number of outliers there can be in a set of data.
What are limits on outliers?
apparently there is no limit to outliers. at least according to everybody else's answers.
Is the median particularly sensitive to outliers in the data?
It is not.
How can you determine which measure of central tendency is best for the set if data?
Mean- If there are no outliers. A really low number or really high number will mess up the mean. Median- If there are outliers. The outliers will not mess up the median. Mode- If the most of one number is centrally located in the data. :)
What is the meaning of 0.79 coefficient correlation?
good correlation
Is correlation a resistant measure?
i think correlatioin is a nonresistant measure because if you take out outliers than only the data that's close together is there...this will increase the correlation closer to -1 or 1, depending on the slope
Is metal nonresistant?
Care to clarify? The question is way too broad to give a useful answer. What type of metal? resistant or non-resistant to what?
Is the correlation coefficient resistant?
No, it is not resistant to changes in data.
In general the median of a data set is more resistant to outliers than the mean.?
Yes, it is.
Is the correlation coefficient r a resistant measure of association?
no
How do you use nonresistant in a sentence?
Nonresistant is defined as the inability to withstand the effect of something, or a person who does not resist force. A sample sentence is "Shale is a nonresistant form of sandstone."
What are the three ways to describe data in a scatter plot?
You can describe if there's any obvious correlation (like a positive or negative correlation), apparent outliers, and the corrlation coefficient, which is the "r" on your calculator when you do a regression model. The closer "r" is to either -1 or 1, the stronger that correlation is.
Which descriptive summary measures are considered to be resistant statistics?
Median is a good example of a resistant statistic. It "resists" the pull of outliers. The mean, on the other hand, can change drastically in the presence of an outlier.The interquartile range is a resistant measure of spread.
How do use nonresistance in a sentence?
