StatdiskComputation Week 1

Week1 project Statistical skills

  1. Opening a file.

Thisactivity is achieved after opening mystadisk window. Blank emptywindow appears which is ready to accept any inputs. In the data toolsmenu choose edit column titles. You can enter the names of the newvariables that are of your interest. You can save the file using thesave option in appropriate direction. This file will be automaticallysaved as Statdisk format and any time you can open it from the windowmenu of statdisk using open file. We shall use a sample of data setfrom Elementary statistics 12 edition for measurements of femalebody,(Wakeham, 2015).

2.Copy and Pasting Option

Oncethe data is entered one can use the copy the selected data from themenu bar and this can be pasted using paste option as in normalformat in Ms word, Excel using the paste command.

3.Sorting the data

Selectthe column in which you want to sort the data. Choose sort commandfrom the Data tool to sort the data using the intent ended formateither ascending or descending.

4.Data Transformation

Choosefrom the open window Data and then sample transformation then inputthe formula to be computed to make the new variable.
