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 ...
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).
We learn how to create indicator variables, change variable classes, add or modify variable levels, collapse variables, and create an additive index

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().

Sometimes we have different variables on a vastly different scale (for example, 0.1 to 1 and 1million to 10million). How can we compare them? One option are indexed charts. Here we show how to create them. This video shows the following tasks: - clear formatting in Google Sheets - enter a formula in Google Sheets that will index our numbers - create a Datawrapper line chart This video doesn't have any audio.

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.

In anticipation of the argument principle, we study the winding number of a closed rectifiable curve. The winding number describes the number of twists performed by the curve about a fixed point not on the curve.
Review of logical indexing, finding duplicate values in a vector, duplicate rows in a data frame or matrix, principal component scores (which are the originial variables transformed into the principal component space), and visualization of the data in the component space. Remember, the loadings are the weights on each variables in a given component. These are then multiplied by the original variables and create scores which is the linear combination of the original variable. The scores are the new transformed variables. The first column of the transformed variables is the first principal component or "latent variable", and the values in that column are the scores. Each row is an observation and the values in that row are that observation's score in the respective principal component (lat...

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...
