You can perform the descriptive statistics on datasets in workbook by using X function Stats on selected range or specific columns
The syntax is as follows:
stats ix:=<active> //on the selecting range stats ix:=wcol(1) //on the 1st column
The following statistical values are calculated:
| Statistic | Stored Result |
|---|---|
| Mean | stats.mean |
| Total | stats.sum |
| Minimum | stats.min |
| Maximum | stats.max |
| Standard Deviation | stats.sd |
| Number of Points | stats.n |
For example:
stats ix:=wcol(1) //view the results stats.mean=; stats.sd=; stats.sum=;
| Notes:
You can also define labels for the variables and use them in later operations, for example: stats ix:=col(a) mean:=m sd:=std sum:=mysum //view the results m=; std=; mysum=; |
The x-function Rowstats can be used across multiple columns to return new dataset which contains the statistics(mean, sd, sem, min, max, n, sum), of each row.
For example:
rowstats irng:=col(1):col(3) mean:=<new> sd:=<new>; //mean and sd of each row will be generated in the new columns rowstats irng:=col(1):col(3) mean:=wcol(4) sd:=<optional>; //output mean of each row to the 4th column
