PDF Files

Creating PDF files:

Here are a few free web page that convert files to PDF over the internet:

I use the following free software to create my PDF files (it leaves no watermark): http://www.primopdf.com/

I also use OpenOffice to create some free PDF files. Open Office is a free Office Suite similar to Microsoft Office (Open Office leaves no watermark): http://www.openoffice.org/

If you want further tips and links for converting to free PDFs, read this site http://www.pruittfamily.com/paul/freepdf.htm or this one http://www.masternewmedia.org/2002/03/31/creating_pdfs_without_adobe_acrobat_part_ii.htm

Types of Statistical Procedures and Their Characteristics

 Statistical Test Independent Variable Dependent Variable Special Feature Example Hypothesis (1) Pearson's r (correlation coefficient) Quantitative Quantitative There is a positive relationship between intelligence and mathematics achievement scores. (2) t-test for independent groups Qualitative Quantitative IV has only 2 categories There will be a difference between boys and girls on mathematics achievement scores. (3) Chi-Square c2 Qualitative Qualitative Both IV and DV may have more than two categories Males will be more likely to drop out of school than females. (4) One-way ANOVA (Analysis of Variance) Qualitative Quantitative IV may have 2 or more categories. There will be a difference among Black, Hispanic, and White students in mathematics achievement scores. (5) Multi-way ANOVA (Analysis of Variance) Several Qualitative Quantitative IVs may have 2 or more categories. There will be a difference among Black, Hispanic, and White, and between male and female, students in mathematics achievement scores. (6) ANCOVA (Analysis of Covariance) 1. Qualitative 2. Covariate may be either qual. or quan., but usually quantitative 3. May also have several additional qualitative and quantitative variables Quantitative Qualitative IVs may have 2 or more categories. Covariates used to make adjustments to DV means. There will be a difference among Black, Hispanic, and White students in mathematics achievement scores after taking into account levels of motivation. (7) Regression Both Qualitative and Quantitative Quantitative Any of the above except for chi-square. Special coding procedures are required to in regression to handle qualitative IVs. (8) Logistic Regression Both Qualitative and Quantitative Qualitative DV is qualitative with only 2 categories Any of the above, except the DV will be binary (e.g., dropout/persist; pass/fail; favor/oppose)
