for details If you use COMSOL Script or MATLAB you can also use interpolation functions in a COMSOL Script or MATLAB function The model. Types of Variables. There are 2 main types of variables: . Independent Variable: . The variable that is changed by the scientist; the ‘. I control. ’ variable. Dependent Variable: . The variable that might change because of what the scientist changes – what is being measured . Reliability & Validity. Fluctuations in Measured Variables. Measured Variables are likely to fluctuate and be influenced by many factors other than the . Conceptual Variable. of interest. Random Error. A Big .

In this section we extend simple linear regression where we had one explanatory variable, and allow for any number of explanatory variables.. We expect to build a model that fits the data better than the simple linear regression model.. Programs in Standard Form. Maximize . Subject. to.  .

Any set of data contains information about some group of individuals, organized by variables. . Designing Investigations. 3 Kinds of Variables. Independent Variable – something that is changed by the scientist. What is tested. What is manipulated. 3 Kinds of Variables. Dependent Variable – something that might be affected by the change in the independent variable. • State-space representation.. • Linear state-space equations.. • Nonlinear state-space equations.. • Linearization of state-space equations.. 2.

Unit 1- Measurement: Nature of Psychological Measurement, Measurement Scales. Nature of Psychological Measurement. Measurement means short and quantitative values. Measurement is a quantitative description of objects, observations and behaviours. In measurement the objects, events, observations and behaviours are described as numbers..
