What can COUNTER do?,COUNTER analyses frequency data typed in using the keyboard. COUNTER cannot read data files from disc. COUNTER can be used to:

适宜

What can UNIVAR do?,UNIVAR calculates descriptive statistics for univariate data and graphically displays the data as a histogram. Data may be entered at the keyboard or retrieved from a data file created by FILER. It is possible to select a single variable from a bivariate or multivariate file.

残酷的地方

What can INFER do?,INFER carries out significance tests and calculates confidence limits for univariate data. Data may be entered at the keyboard or retrieved from a data file created by FILER (except for analysis of variance where only keyboard data entry is available).

施加

What can BIVAR do?,BIVAR performs correlation and regression analysis for bivariate data. Data may be entered at the keyboard or retrieved from a data file created by FILER. It is also possible to select any two variables from a multivariate file created by FILER. BIVAR can be used to:

How do I modify the programs?,FILER, COUNTER, UNIVAR, INFER, BIVAR and POLYVAR have been compressed by tokenising the BASIC keywords and removing spaces. If you wish to modify the programs you will need to retype the complete line that you change.

How much data can I enter?,nsformation option within BIVAR then you can analyse fewer data than if you did not select this option. If you subsequently select an option for which the data space becomes exceeded, the program will crash with a fatal error.

说明

How can I use a graphics dump?,e first number that appears on the screen after the name of the routine is the required load address. If your graphics dump does not load at &A00 then you will need to alter line 270 in UNIVAR and line 1143 in BIVAR.
