The selected topics illustrate the basic assumptions of most statistical methods and\/or have been demonstrated in research to be necessary components of one&#8217;s general understanding of the &#8220;quantitative nature&#8221; of reality (Nisbet, et al., 1987). Because of space limitations, we will focus mostly on the functional aspects of the concepts discussed and the presentation will be very short.<\/p>\n<p>Further information on each of those concepts can be found in the Introductory Overview and Examples sections of this manual and in statistical textbooks. Recommended introductory textbooks are: Kachigan (1986), and Runyon and Haber (1976); for a more advanced discussion of elementary theory and assumptions of statistics, see the classic books by Hays (1988), and Kendall and Stuart (1979).<\/span><\/p>\n<hr size=\"1\" \/>\n<table border=\"0\">\n<tbody>\n<tr>\n<td width=\"45%\"><span style=\"font-size: medium\"><a name=\"Topical Index\"><\/a><\/span><\/p>\n<ul>\n<li><a href=\"http:\/\/www.statsoft.com\/textbook\/elementary-concepts-in-statistics\/#What are variables\"><span style=\"font-size: medium\">What are variables?<\/span><\/a><\/li>\n<li><a href=\"http:\/\/www.statsoft.com\/textbook\/elementary-concepts-in-statistics\/#Correlational vs. experimental research\"><span style=\"font-size: medium\">Correlational vs. experimental research<\/span><\/a><\/li>\n<li><a href=\"http:\/\/www.statsoft.com\/textbook\/elementary-concepts-in-statistics\/#Dependent vs. independent variables\"><span style=\"font-size: medium\">Dependent vs. independent variables<\/span><\/a><\/li>\n<li><a href=\"http:\/\/www.statsoft.com\/textbook\/elementary-concepts-in-statistics\/#Measurement scales\"><span style=\"font-size: medium\">Measurement scales<\/span><\/a><\/li>\n<li><a href=\"http:\/\/www.statsoft.com\/textbook\/elementary-concepts-in-statistics\/#Relations between variables\"><span style=\"font-size: medium\">Relations between variables<\/span><\/a><\/li>\n<li><a href=\"http:\/\/www.statsoft.com\/textbook\/elementary-concepts-in-statistics\/#Why relations between variables are important\"><span style=\"font-size: medium\">Why relations between variables are important<\/span><\/a><\/li>\n<li><a href=\"http:\/\/www.statsoft.com\/textbook\/elementary-concepts-in-statistics\/#Two basic features of every relation between variables\"><span style=\"font-size: medium\">Two basic features of every relation between variables<\/span><\/a><\/li>\n<li><a href=\"http:\/\/www.statsoft.com\/textbook\/elementary-concepts-in-statistics\/#What is &quot;statistical significance&quot;
