  • SPSS for newbies:adding variables to make scores from questionnaire data

    Very often students who have questionnaire data ask me whether they can add together some similar variables to create a new variable that summarizes the meaning of all the questions that go into it, for example if you have a load of questions about the service of an airline, the sum of those questions gives a new variable that may be interpreted as airline satisfaction score. The answers is YES (that new variable is called a score/index), but there are things to watch out for. Keywords: index, composite score, attribute, trait, items, unit weighted scores, weighted scores, reliability, MEAN().

Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it! About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

This video illustrates how to calculate a correlation in Excel on three variables using the Data Analysis Toolpak. Correlation in Excel Data Analysis ToolPak Pearson Correlation in Microsoft Excel Video Transcript: In this video I want to take a look at how to calculate the correlation coefficient in Microsoft Excel when I have more than two variables. So in this example I have SAT score, social support and this was recorded in college, and then college GPA. So we have three variables and what I want to do is get the correlation between all pairs of variables. So the correlation of SAT with social support, the correlation of SAT with college GPA, and then the correlation of social support with college GPA. So to do that I want to go ahead and select Data and then Data Analysis and then when this window opens up I want to go to Correlation and then click OK. Now here I need to select the area of my variables and it's already selected here but let's go ahead and redo that. So start with the first label SAT score and scroll all the way down until we have all the data selected. Notice that says B1 through D31 so those are all the cells that are of interest. And then notice that I've gone ahead and selected my labels which I wanted to do so I want to make sure I check this box Labels in First Row and then notice it says Grouped by Columns and that's right each variable is in a separate column so that looks great so let's go ahead and click OK. And it opens up the results in a new worksheet. I'm going to go ahead and expand these columns by double-clicking on them so we can see the information better here and then I'll also go ahead and dial down these decimal places here and we'll just take them to two decimal places. OK now I'm going to highlight the correlation coefficients so they're easier to see. And then let's go ahead and make this font a little larger as well so it's easier to see and I'll have to re- expand just a bit more. OK so these are our correlation results and notice here I have SAT Score, Social Support, and College GPA and here where a column intersects with a row that indicates the correlation. So the correlation .03 is the correlation or relationship between the SAT score and social support and that's very small. And then SAT correlates with college GPA .62 which is much higher that's a pretty strong correlation. And then finally social support correlates with college GPA .35. Now in this video what we're looking at when we're calculating the Pearson correlation coefficient which is what this is. When we run this analysis in Excel we get these correlation coefficients output it's important to note here that all we're getting is the descriptive statistic or the correlation between the two variables. But we haven't tested these for statistical significance. So while we know that the correlation here between college GPA and SAT scores .62 we don't know for certain at this point whether that correlation is significantly different from zero. It probably is just from experience here but we don't know that by looking at this alone and we don't know for example is .35 statistically significant this correlation between social support and college GPA. We can't tell that from this analysis. To know that we need to run another procedure in Excel which I've done in another video which I'll link to in this video for those who are interested. But it is important to be aware of here that running this procedure while definitely worthwhile it doesn't state whether a given correlation is statistically significant or not. So in other words we don't know whether this .35 is significantly different from zero or no relationship. We need to establish that by conducting a hypothesis test and unfortunately in Microsoft Excel it doesn't come out automatically when you run the correlation procedure but instead we need to run a different analysis. OK that's it for running the Pearson correlation for multiple variables in Microsoft Excel. Thanks for watching. YouTube Channel: https://www.youtube.com/user/statisticsinstructor Subscribe today!

 Are Assigned A Data Type
 The Data Can Change Throughout The Program's Operation
 The Data Entered Must Be The Same Data Type As Assigned To The Variable Variables are a name that is given to the data. The name must not start with a number or character that is not a letter. Also, the name of the variable must not be a reserved name like PRINT, INPUT, LET, ABS, BEEP, etc. There are two ways to declare a variable in QBasic. The first is to put a data type symbol after the name $ String % Integer & Long ! Single # Double && _INTEGER64 (QB64 Only) ## _FLOAT Examples: MyName$ Num1% Num2! Answer! The second way is the preferred way since Visual Basic uses this method. Becoming accustom to this way will help the transition from QBasic to Visual Basic. DIM is used to make variables of a data type. DIM [Variable Name] As Data Type DIM [Variable Name] AS STRING DIM [Variable Name] AS INTEGER DIM [Variable Name] AS LONG DIM [Variable Name] AS SINGLE DIM [Variable Name] AS DOUBLE DIM [Variable Name] AS _INTEGER64 DIM [Variable Name] AS _FLOAT Examples: DIM MyName AS STRING DIM Num1 AS INTEGER DIM Num2 AS SINGLE DIM Answer AS SINGLE Remember that selecting the right data type for the variable is very important to make the program run properly.
