Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "we will focus on the Extreme Values table and the boxplot."

A block of code is set as follows:

FREQUENCIES VARIABLES=Price
  /FORMAT=NOTABLE
  /PERCENTILES=1.0 5.0 10.0 25.0 50.0 75.0 90.0 95.0 99.0 
  /STATISTICS=MINIMUM MAXIMUM
  /HISTOGRAM
  /ORDER=ANALYSIS.

Any command-line input or output is written as follows:

RECODE quality (1 thru 3=0) (4 thru 5=1) INTO qualsatpos.
VARIABLE LABELS qualsatpos 'Satisfied with Quality.

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "In order to download new modules, we will go to Files | Settings | Project Name | Project Interpreter."
