What else can I help you with?
Does outliers affects data?
No. Outliers are part of the data and do not affect them. They will, however, affect statistics based on the data and inferences based on the data.
Why is the interquartile range a more appropriate measure for spread than the range?
the interquartile range is not sensitive to outliers.
What is the primary disadvantage of using the range to compare the variability of data sets?
The range is very sensitive to outliers. Indeed if there are outliers then the range will be unrelated to any other elements of the sample.
What are the limits on outliers?
there are no limits to outliers there are no limits to outliers
Is range is not considered to be an index of despersion?
The sample range could be used as an index of dispersion. However, there are objections. One is that this statistic is obviously sensitive to outliers. Another is that for many population distributions there are measures with much better characteristics, even ignoring the problem of outliers.
Is the median particularly sensitive to outliers in the data?
It is not.
Disadvantages of the mean in statistics?
the mean is affected by outliers
Can you safely remove outliers from scatter charts?
You can only do it if either the outliers are way out - so far that they must be odd, so far that there can be no argument, no need for statistics to prove them to be outliers, or you need to prove that they are outliers using statistics - something like Grubb's test. To do that, the simplest way is software.

Is the slope of the Least Squares Regression Line very sensitive to outliers in the x direction with large residuals?
Yes, it is.
What are the limits on outliers?
there are no limits to outliers there are no limits to outliers
What is the measurement of variability that is most distorted by the presence of outliers?
The range is most distorted.

What do outliers indicate?
In statistics, outliers are values outside the norm relative to the rest of collected data. Many times they can skew the results and distort the interpretation of data. They may or may not indicate anything significant; they might just be an anomalous data point that is not significant. It is difficult to tell.
What is M in statistics?
In statistics, "M" often represents the median, which is a measure of central tendency that divides a dataset into two equal halves. The median is the value at the midpoint when data points are arranged in ascending order, making it less sensitive to outliers compared to the mean. In some contexts, "M" may also refer to the mean or expected value, depending on the specific statistical discussion. Always consider the context to determine its exact meaning.
