Khan Academy. 20 Strangers Kiss for the First Time. Using SPSS for bivariate and multivariate regression. When you select the "linear regression" function, SPSS will provide a wizard that looks like the one portrayed in Figure I: Figure 1 In Figure 1, the list that you see in the left-hand window lists variables by their variable label (rather than the eight character variable name that you probably have in your codebook).
Select the variables you want to analyze, and use the arrow button to send them to the appropriate right-handed windows. The dependent variable (the variable's whose variations you want explain) in your model goes in the top right-hand window (only one variable can be analyzed at a time; if you are interested in running a similar model with different dependent variables, you will need to repeat the procedure for each dependent variable).
Next, one or more independent variables should be listed in the bottom right-handed window. You may select multiple variables at at time by holding down the "control" button on your key board as you click on various variables. 1. Figure 2. Scatter Plots. Statisticians and quality control technicians gather data to determine correlations (relationships) between such events. Scatter plots will often show at a glance whether a relationship exists between two sets of data. Let's decide if studying longer will affect Regents grades based upon a specific set of data. Given the data below, a scatter plot has been prepared to represent the data. Remember when making a scatter plot, do NOT connect the dots. Notice: Certain values may have more than one result, such as (7,90) and (7,85) and (7,100).
The data displayed on the graph resembles a line rising from left to right. If the slope of the line had been negative (falling from left to right), a negative correlation would exist since the slope of the line would have been negative. If the plot on the graph is scattered in such a way that it does not approximate a line (it does not appear to rise or fall), there is no correlation between the sets of data. 40 websites that will make you cleverer right now.

Veerendra Chandrappa. High Tech Reflection Strategies Make Learning Stick. Routinely asking students to ponder -- deeply and seriously -- what and how they've learned could be the "mind's strongest glue. " Share to Learn: Teacher George Mayo helps students Fernando, Binyam, and Johana edit their blog posts before publishing them. In their blogs, the students record podcasts and write about a novel they read. Credit: Courtesy of George Mayo When he started teaching middle school five years ago, George Mayo immediately began using blog posts to teach writing because he knew that there are myriad benefits to using the technology.
Chief among them, Mayo says, is that blogs "naturally put an emphasis on reflection. " At his Maryland middle school, Mayo asks his students -- many of whom struggle with reading and writing -- to create at least one blog post a week. Indeed, as Mayo anticipated, blogs have consistently inspired the emerging writers in his classroom to reflect on their progress. "It's powerful stuff for students," Mayo adds. A Critical Piece to Learning. Praxis makes perfect.
