Scientific experiments aim to provide empirical data which can be used to falsify null hypotheses and thus aim to provide a more coherent picture, or theory, of the natural world. Variables that are not dependent on any parameter or factor are independent variables and the ones which ...

Is the number of damaged chromosomes on a petri dish following irradiation an example of a discrete variable or a continuous variable? Explain. What should be the nature of the dependent variable? Cluster analysis can only be performed on continuous variables. State true or false. Consider the f...

Lines –where a relationship (correlation) between 2 variables is expected, but no connection, a line is used.Figure 1- an example of a conceptual frameworkOther influencing variablesAside from the independent and dependent variables there are other variables that can come into play that influence ...
In inferential statistics, linear regression is the most often employed type of regression. The dependent variable’s response to a unit change in the independent variable is examined through linear regression. These are a few crucial equations for regression analysis using inferential statistics:...

The marginal effects for the unconditional expected value of the dependent variable, E(y*), where y* = max(a, min(y,b)), are . mfx compute, predict(ys(a, b)) where a is the lower limit for left censoring and b is the upper limit for right censoring. ...
Assumption #3: Your dependent variable should be measured at the ordinal or continuous level. Examples of ordinal variables include Likert scales (e.g., a 7-point scale from strongly agree through to strongly disagree), amongst other ways of ranking categories (e.g., a 5-point scale explaini...
An extraneous variable is characterized as an unaccounted for, an unstudied external factor connected to the independent variable somehow and may impact the outcome of the dependent variable. As a researcher, it is essential to account for and control extraneous variables because they can undermine ...
