What Is data that does not fit with the rest of the data set?
Anomalous 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. :)
What are extremely high or low values in a data set called?
Values that are either extremely high or low in a data set are called 'outliers'. They are typically 3 standard deviations or more from the mean.
Is the median particularly sensitive to outliers in the data?
It is not.
What is an outlier in math?
Outliers are basically numbers, in a set of numbers, that don't belong in that set and/or that stand out. For example, in the data set {3, 5, 4, 4, 6, 2, 25, 5, 6, 2} the value of 25 is an outlier. For a set of numerical data (a set of numbers), any value (number) that is markedly smaller or larger than other values is an outlier. This is the qualitative definition. Mathematically, a quantitative definition often given is that an outliers is any number that is more than 1.5 times the interquartile range away from the median. However, this is not definitive and in some cases other definitions will be used.
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.
What Is data that does not fit with the rest of the data set?
Anomalous Data
In general the median of a data set is more resistant to outliers than the mean.?
Yes, it is.
What is grubbs algorithm?
Grubbs test is used to detect outliers in a univariate data set.
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. :)
Can outliers affect the symmetry of the data?
an outliers can affect the symmetry of the data because u can still move around it
Why do they invented the stem and the leaf plot?
to organize your data set and figure out mean, median, mode, range, and outliers.
What are extremely high or low values in a data set called?
Values that are either extremely high or low in a data set are called 'outliers'. They are typically 3 standard deviations or more from the mean.
When given a set of data that appears to contain outliers which measure of central tendency is most appropriate to use?
Coefficient of Determination
