# Basic Statistics

outlier
For calculating the statistical properties of a data-set the data must entered in 1. the input table. The result of each column will be displayed in the underlying result array 3. and Graph image 2.

Select Basic in the statistical mode drop-down menu to use the Basic Statistics functions

## 1. Input table

The Input Table is for the data to be analyzed. If a data point is out of tolerance the text will be colored red, the tolerance borders must be entered in the result array 3. If a data point could be an outlier the cell is gray and for a extreme outliers dark gray. See the legend 6.
The amount of decimals behind the point can be changed in the box in the upper left corner.

## 2. Graphs

The graph of the data-set is life updated after data is entered. With the graph selector 8. the type of graph can be chosen. The graph can be made invisible or visible with the selector in the upper left corner Graph. By clicking on a graph a bigger version of the graph will be displayed in a pop-up.

## 3. Result table outlier

In this table the result will be displayed according the selection in the selection area 9. For comparing data sets put in the comparing column (the first row) the comparing column and this will be used for; t-test, F-test, and correlation calculations.
Row 2-4 is for the tolerance borders and nominal value, these will be displayed in the graphs and used for; Cp, Cpk and the % out of tolerance calculation.

## 9. Selection area

In the selection area the calculation to be executed can be selected.
 Mean Mean n Size of data set Median Median STDEV Standardevidation % Cp Cpk Cp Cpk % out of tolerance Difference Difference in mean with the comparing Column t-test Test for difference in mean Normality test Checks if the data set is distributed according the normal distribution. F-test Test for difference in variation Kurtosis If the data set is flat or peaked distributed Skewness If the data set is symmetrical distributed Correlation Correlation between 2 data sets and the Regression Min/Max Shows the minimum and maximum value

## 5. Statistical mode

When selecting DOE the DOE layout will be displayed.

## What statistical tests

 Test what With what statistical test Difference in Mean t-test Difference in Mean between multiple data sets One way Anova Difference in Variation Variation F-test If data set is normal distributed Anderson Darling normality test Is the data according specification Cp Cpk % out of tolerance If there is relation between two data sets Correlation Calculates the relation between data sets Regression Difference in two proportions (Data set with only good or false results) Proportions
