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.

SPSS for questionnaire analysis:  Correlation analysis
Basic introduction to correlation - how to interpret correlation coefficient, and how to chose the right type of correlation measure for your situation. 0:00 Introduction to bivariate correlation 2:20 Why does SPSS provide more than one measure for correlation? 3:26 Example 1: Pearson correlation 7:54 Example 2: Spearman (rhp), Kendall's tau-b 15:26 Example 3: correlation matrix I could make this video real quick and just show you Pearson's correlation coefficient, which is commonly taught in a introductory stats course. However, the Pearson's correlation IS NOT always applicable as it depends on whether your data satisfies certain conditions. So to do correlation analysis, it's better I bring together all the types of measures of correlation given in SPSS in one presentation. Watch correlation and regression: https://youtu.be/tDxeR6JT6nM ------------------------- Correlation of 2 rodinal variables, non monotonic This question has been asked a few times, so I will make a video on it. But to answer your question, monotonic means in one direction. I suggest you plot the 2 variables and you'll see whether or not there is a monotonic relationship there. If there is a little non-monotonic relationship then Spearman is still fine. Remember we are measuring the TENDENCY for the 2 variables to move up-up/down-down/up-down together. If you have strong non-monotonic shape in the plot ie. a curve then you could abandon correlation and do a chi-square test of association - this is the "correlation" for qualitative variables. And since your 2 variables are ordinal, they are qualitative. Good luck

Correlation & Regression: Concepts with Illustrative examples
We can use scatter plots to understand the relationships between variables, but it is applied only for obvious relationships like Temperature and Viscosity. Sometimes, it is not possible to comment about relationship between variables only looking at the graph. “CORRELATION & REGRESSION” are very important mathematical concepts to define relationship between variables. This is the topic for video. I have tried to explain these concepts with the help of practical examples which will be very easy to understand. I have also explained the procedure about how to create a “CORRELATION & REGRESSION ANALYSIS” in Microsoft Excel. Everything is with steps, snapshots and examples, which will be very easy to understand. I have also covered statistics part like how to read and understand “SIGNIFICANCE F and P-values” I am sure, you will liked it.

Correlation Doesn’t Equal Causation: Crash Course Statistics #8
Today we’re going to talk about data relationships and what we can learn from them. We’ll focus on correlation, which is a measure of how two variables move together, and we’ll also introduce some useful statistical terms you’ve probably heard of like regression coefficient, correlation coefficient (r), and r^2. But first, we’ll need to introduce a useful way to represent bivariate continuous data - the scatter plot. The scatter plot has been called “the most useful invention in the history of statistical graphics” but that doesn’t necessarily mean it can tell us everything. Just because two data sets move together doesn’t necessarily mean one CAUSES the other. This gives us one of the most important tenets of statistics: correlation does not imply causation.

How to Calculate a Correlation Matrix in Excel (Three or More Variables)
Check out our brand-new Excel Statistics Text: https://www.amazon.com/dp/B076FNTZCV This video illustrates how to calculate a correlation in Excel on three variables using the Data Analysis Toolpak. YouTube Channel: https://www.youtube.com/user/statisticsinstructor 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!
