Statistics 2080B Minitab Hints
Every time you go into MINITAB you need to make a new outfile. You should not have any spaces or punctuation in your outfile name. A short word is best for an outfile name.
Don't forget to close your outfile before leaving MINITAB. To do this, use the command
MTB > NOOUTFILE
You can only print after you have gone out of MINITAB and back to gs, that is, when you see the $ prompt.
$ lpr -J aname filename.LIS
To look at which files are in your directory, type ls at the $ prompt.
Note that the files with the .LIS extension are the files that you can print, and the files with the .MTW extension are the files that you can retrieve.
To look at the contents of a particular file, type more filename after the $ prompt
$ more filename (filename is the name of the file you want to look at)
If you have made a mistake in entering data you can use the LET command to make the correction. Say the mistake was the 4th row in C8. The value should have been 19, but you typed in 190 by mistake. To correct this
MTB > LET C8 (4) = 19
When you press enter, the MTB prompt comes up meaning that the data change has been made. If you want to check that the changes have been made, type PRINT C8 at the MTB prompt.
Suppose you need to delete a data point; say that the point to be deleted is the sixth row of column 4.
MTB > DELETE 6 C4
As above, when you press enter, the MTB prompt comes up meaning that the data change has been made.
You can delete data from more than one column at a time. Suppose you want to delete the seventeenth row from columns 5,6,7,and 28.
MTB > DELETE 17 C5 C6 C7 C28
Suppose you forgot to enter a point in the data set. Then use the command INSERT to correct your data set. You can find out how to use this command by typing HELP INSERT at the MTB prompt.
Remember that you can find out how to use any command in MINITAB by typing HELP followed by the command name. If you want to find out how to use a certain subcommand, type help followed by the name of the command and the name of the subcommand.
1. You want to find out how to use the HISTOGRAM command
MTB > HELP HISTOGRAM
2. You want to find out how to use the PREDICT subcommand of the REGRESS command.
MTB > HELP REGRESS PREDICT
The command HELP displays information about MINITAB
|a list of all command topics||HELP COMMANDS|
|a list of all overview topics||HELP OVERVIEW|
|information on a command||HELP commandname [subcommandname]|
NOTE: I have used capital letters to indicate the commands; however, MINITAB is not case sensitive, so you may use lower case letters for both the commands and the columns. For example,
describe c1 will work just as well as DESCRIBE C1
