Identify Outliers

Use IQR (Q3-Q1) to detect anomalies: values outside the range [Q1-1.5*IQR, Q3+1.5*IQR] are generally considered statistical outliers.

Suggerimenti

  • You can paste data from spreadsheets: copy a column and paste it directly, each row becomes a number.
  • IQR is useful for identifying outliers: values outside the interval [Q1-1.5*IQR, Q3+1.5*IQR] are considered anomalous.
  • For asymmetric distributions, the median is often more representative of the mean.

What is the difference between mean and median?

Mean is the sum of all values divided by their count. Median is the central value when data is ordered. Median is more robust to outliers.

What does standard deviation indicate?

Standard deviation measures how values deviate from the mean. A low value indicates data concentrated near the mean, a high value indicates highly dispersed data.

What is fashion if it's not shown?

Fashion is the value that appears most frequently. If every value has a unique frequency (frequency 1), there is no fashion and it is indicated as "None".

What are Q1, Q3 and IQR?

Q1 (first quarter) is the value below which 25% of data falls, Q3 the 75%. The IQR (Interquartile Range) is Q3-Q1 and represents the spread of the middle 50% of data.

What separators are supported?

You can use commas, periods and semicolons, or line breaks. The calculator handles all these formats automatically.
