There is no agreed definition of an outlier and consequently, there is no simple answer to the question. The number of outliers will depend on the criterion used to identify them.
If you have observations from a normal distribution, you should expect around 1 in 22 observations to be more than 2 standard deviations from the mean, and about 1 in 370 more than 3 sd away. You will have more outliers if the distribution is non-normal - particularly if it is skewed.
What else can I help you with?
What is it called when the minimum and maximum values in a data set?
They are called outliers
What are data points that do not fit with the rest of a data set?
Data points that do not fit with the rest of a data set are known as outliers. These values are significantly different from the majority of the data, either much higher or lower, and can skew statistical analyses. Outliers may arise from variability in the data, measurement errors, or they could indicate a novel phenomenon worth investigating. Identifying and understanding outliers is crucial for accurate data interpretation.
What is Data that does not fit with the rest of a data set?
Data that does not fit with the rest of a data set is known as an outlier. Outliers can skew statistical analyses and distort the interpretation of data. They can be caused by errors in data collection, measurement variability, or may represent true but rare occurrences in the data set. Identifying and handling outliers appropriately is crucial in ensuring the accuracy and reliability of data analysis results.
Can outliers affect the symmetry of the data?
an outliers can affect the symmetry of the data because u can still move around it
How many data sets does a outliers have?
Each outlier is a single point in the outcome space.
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 data that does not fit well with the rest of a data set.?
They are called extreme values or outliers.
What is it called when the minimum and maximum values in a data set?
They are called outliers
Do they have outliers in a data set?
If the data numbers are all really close together than no. But if the data has numbers; for example: 12,43,45,51,57,62,90 (12 and 90 are the outliers) which are really far aprt, than yes.

Identifying and understanding outliers is crucial for accurate data interpretation.
What Is data that does not fit with the rest of the data set?
Anomalous Data
How would you explain the outliers in chemistry?
In chemistry, outliers are data points that deviate significantly from the rest of the data set. Outliers can result from measurement errors, experimental uncertainties, or unexpected reactions. It is important to identify and address outliers in data analysis to ensure accurate and reliable results.

What is grubbs algorithm?
Grubbs test is used to detect outliers in a univariate data set.
In general the median of a data set is more resistant to outliers than the mean.?
Yes, it is.
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.
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. :)
