Learn how to recode variables and compute and index variable using SPSS.
Download file: https://people.highline.edu/mgirvin/ExcelIsFun.htm 1. See how to do a three way lookup when there are two row header variables (criteria) and one column header (criteria) variable using INDEX and MATCH functions for a normal two way lookup, but with the two row headers joined to create a single row header criteria. In essence, three way lookup is turned into a standard two way lookup. Also see IFERROR function.
Learn how to draw patterns such as a maze or vortex with NCLab Turtle, using for loops and modifying the counting or index variables. Set beginning and ending values for the index, write operations on the index within the body of the for loop. TURTLE CODING COURSE: LEARN PROGRAMMING THROUGH ART The Turtle Coding course is an excellent visual introduction to Python programming. Students create beautiful objects including pendants, mosaics, ornaments, cookie cutters, round containers, vases and even chess figures. Their creations can be printed on 3D printers and cut out of wood or plastic on laser cutters. While writing programs for the Turtle, students become proficient in using variables, loops and functions as well as in Python code syntax, formatting and debugging. The course require...
match and index tutorial. These 2 functions are very often used together in place of vlookup. This example looks up IRS witholding for (1) wages, (2) marital status, and (3) number of deductions. 2 and 3 are combined in a single table (M2, S0, S3, etc.)
Let's go on a journey and learn about indexes and scales as a way of measurement in research!
Introduction to optimal control within a course on "Optimal and Robust Control" (B3M35ORR, BE3M35ORR) given at Faculty of Electrical Engineering, Czech Technical University in Prague. Motivation for optimal control; formulation of optimal control criterion (aka cost function, performance index); identification of optimization variables (either controller parameters or control signals).

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 co...

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().

This video describes how to standardize variables (converting variables into z-scores based on a standard normal distribution) and how to create an index score from variables on different scales (3:27). This video includes a brief reminder of how to read the exponential notation sometimes used by R (at 4:30).
