Meaning Of Outlier In Math
A value in a data set that lies far outside of a pattern they establish.
Meaning of outlier in math. 90 86 15 86 92 15 would be an outlier in this data set. An outlier in a probability distribution function is a number that is more than 1 5 times the length of the data set away from either the lower or upper quartiles. An outlier may be due to variability in the measurement or it may indicate experimental error. As you can see in the figure above most of the data points cluster around the straight line fairly closely.
An outlier is a number completely. Multiplying the interquartile range iqr by 1 5 will give us a way to determine whether a certain value is an outlier. An outlier can cause serious problems in statistical analyses. Outliers are values that lie outside the other values.
If we subtract 1 5 x iqr from the first quartile any data values that are less than this number are considered outliers. For example in the scores 25 29 3 32 85 33 27 28 both 3 and 85 are outliers. Oulier means something that sticks out in math like in the number 50 51 53 54 100. Specifically if a number is less than q1 1 5xiqr or greater than q3 1 5xiqr then it is an outlier.
However the single outlier does not and is far away from the pattern established by the other points. An outlier in math is a point that is separate from the rest of the points. The latter are sometimes excluded from the data set. What do we do with them.
When we collect data sometimes there are values that are far away from the main group of data. An outlier is a number in a data set that is much smaller or larger than the other numbers in the data set.

In statistics an outlier is a data point that differs significantly from other observations.
