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 recode variables and compute and index variable using SPSS.
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...
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).

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.)
This video reviews the scales of measurement covered in introductory statistics: nominal, ordinal, interval, and ratio (Part 1 of 2). Scales of Measurement Nominal, Ordinal, Interval, Ratio YouTube Channel: https://www.youtube.com/user/statisticsinstructor Subscribe today! Lifetime access to SPSS videos: http://tinyurl.com/m2532td Video Transcript: In this video we'll take a look at what are known as the scales of measurement. OK first of all measurement can be defined as the process of applying numbers to objects according to a set of rules. So when we measure something we apply numbers or we give numbers to something and this something is just generically an object or objects so we're assigning numbers to some thing or things and when we do that we follow some sort of rules. Now in ...

We continue to look at basic tolls of R. in this video we look at indexes and logical variables to isolate different indexes
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).
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().
(Index: https://www.stat.auckland.ac.nz/~wild/wildaboutstatistics/ ) Plotting numeric variables shows us interesting characteristics of our data. In this video we’ll explore pulse rates and household incomes and learn how to describe what we see. After you’ve watched this video, you should be able to answer these questions How is a stacked dot plot constructed? What are the four types of things we look for in dot plots? What is the common name for the mean? How does the mean relate to the dot plot? What property defines the median? When do the mean and median tend to be very similar, and when can they be quite different? Why might we prefer the median to the mean for personal incomes?
