An index is an indirect shortcut derived from and pointing into a greater volume of values, data, information or knowledge. Index may refer to:
Learn how to recode variables and compute and index variable using SPSS.
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().
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...

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).
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).
Full lecture: http://bit.ly/D-Tree Which attribute do we select at each step of the ID3 algorithm? The attribute that results in the most pure subsets. We can measure purity of a subset as the entropy (degree of uncertainty) about the class within the subset.
Big crossover topic from Algebra 1 to Algebra 2, on exponents. Here we multiply exponents, divide exponents, and raise them to powers. I hope this video can improve your abilities, exponentially! YAY MATH! Please visit yaymath.org Video copyright (c) Yay Math
This is a model fit exercise during a CFA in AMOS. I demonstrate how to build a good looking model, and then I address model fit issues, including modification indices and standardized residual covariances. I also discuss briefly the thresholds for goodness of fit measures. For a reference, you can use: Litze Hu & Peter M. Bentler (1999) Cutoff criteria for fit indexes in covariance structure analysis: Conventional criteria versus new alternatives, Structural Equation Modeling: A Multidisciplinary Journal, 6:1, 1-55

Derived variables are created from other variables. For example, from Humidity and temperature variables we can generate the Temperature and Humidity Index (THI).
Part 1 - Merge data by adding variables. In this example, we will use data from the Social Vulnerability Index data set and merge in information from the 2016 US Presidential Election. Here we have data sets that have different variables but the same cases.

Personal guidance from your Mentors ---------------------------------------------------------------------------------------- A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in PL/SQL has a specific data type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory and the set of operations that can be applied to the variable. The name of a PL/SQL variable consists of a letter optionally followed by more letters, n...

This is the first C++ tutorial movie, and in this video I will be discussing how to set up Eclipse to run C++ programs. Then we will discuss how to define and initialize variables with different data types and print them out. Then I will show you how to print the size of each data type and tell you some dangers of overflow and uninitialized variables.

Dr. Steve Garrity's virtual seminar "Canopy 101: Leaf Area Index - Theory, Measurement, Application" discusses the different methods available for measuring LAI. The theory, advantages, and disadvantages of each method will be covered. Leaf Area Index (LAI) is one of the most widely measured variables used to describe plant canopies. The traditional approach to measuring LAI required destructive harvesting and measurement of every leaf within a given area of plant canopy. Fortunately, advances in theory and sensor technology have provided several alternative methods for rapidly and non-destructively estimating LAI.

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. Watc...
