The first step in learning how to read a topographic map is to understand how to interpret the lines, colors and symbols. On these maps, you'll see large expanses of green for vegetation, blue for water and gray or red for densely built up areas. Houses are small black squares. You'...

When to use the STDEV.P function and the STDEV.S function? Use STDEV.P if you have the full population data. Use STDEV.S if you have a sample of limited data from a larger population. STDEV.P will result in a lower standard deviation compared to STDEV.S on the same data. Sample st...
or beta of zero, is located at the y-intercept. The purpose of the graph is to identify the action, or slope, of the market risk premium. In financial terms, this line is a visual representation of therisk-return tradeoff.
Validityis theevidence provided to support score interpretations. For example, we might interpret scores on a test to reflect knowledge of English, and we need to provide documentation and research supporting this. There are several ways to provide this evidence. A straightforward approach is to est...
The LINEST function will output an array of results containing the regression coefficients, including the slope (coefficient) and y-intercept. That's it! Now you have the LINEST results to analyze and interpret the linear regression of your data. In this example, the linear regression equation ...
So the utility of contrast coding is that the researcher can pick and choose how she/he wants to interpret the regression coefficients, in a way that’s statistically well-founded (e.g., it does not require running many post hoc tests) without changing the model (in the sense that the ...
Correlation research is a core step in understanding your data (such as from survey research) or the relationship between variables in your dataset.
This tutorial will guide you through the process of performing linear regression in R, which is important programming language. By the end of this tutorial, you will understand how to implement and interpret linear regression models, making it easier to apply this knowledge to your data analysis ...
The main difference is inhow these topics are approached.For example, in a basic stats class, confidence intervals are introduced as a way to describe the distribution ofparameters(i.e. how spread out your estimated results are). The focus is on how to make and interpret these intervals. Wi...
