The IBM SPSS Statistics v.20.x86-x64 Multilingual package is a comprehensive integrated statistical analysis environment for researchers, students, and business professionals that simplifies data analysis and answers complex statistics questions with a few clicks of the mouse. It helps you turn raw data into answers to your questions about people, markets, and trends. In this article I will be explaining how to use this software through an example involving two different datasets from the National Center for Educational Statistics (NCES) website: "Table A3: Percentage of public school teachers who reported typically teaching in their content area in 1990" and "Table A4: Percentage of public school teachers who reported typically teaching in their content area in 2008". The primary objective will be to help users understand how to take two datasets from the NCES website, isolate the variables that are of interest, analyze these variables in SPSS Statistics v.20.x86-x64 Multilingual and revise the results in the same manner in Excel. We shall assume that these two steps are simpler than using other software. Following are some key questions for this example: 1) How do we take two datasets from an online database? The first step is identifying "All" or "All" data sets that are listed on the databases' home page. From there, click on either dataset name to select it for download. The following screenshot shows a "Table A3" dataset, which is located here. 2) Once the datasets have been selected, they can be opened to be browsed and studied. The next step is to open the files in the SPSS Statistics v.20.x86-x64 Multilingual software. By default, these files are stored in the user's downloads folder under a "Statistics_20_x86" folder ("Statistics_20_x64" for x64 machines). The following screenshot shows "Bike Theft (All)", which has been downloaded and placed in the SPSS Statistics v.20. x86-x64 Multilingual folder. 3) Open the "Stats" menu, then click on either dataset name to select it for analysis. Selecting one of these files will open the "Statistical Tests" window, where the data should be analyzed. The following screenshot shows "Bike Theft (All)", which has been selected by clicking on one of its file names in the SPSS Statistics v.20.x86-x64 Multilingual menu. The statistical tests are listed in tables (A through E). 4) Choose a statistical test from the Statistic window. The following screenshot shows a "t-statistics table" from a "Bike Theft (All)" data set. It indicates that, in 1990, 12% of public high school teachers reported teaching in their content area; while in 2008 only 5% reported teaching in their content area. This statistic is statistically significant because it p < .001 (or less than 1%), which is less than the accepted significance level (0.05). 5) To further examine this result, we can select any numerical variable and use it to create a box plot and histogram. eccc085e13
