Answer :
We can reduce list of predictor variable by regression involves employing a linear relationship to attempt to predict the Y variable from the X variable, i.e., the worker's PEFR value is decreased by -4.185.
Based on current circumstances, a predictor variable is used to forecast a future result. This variable also goes by the titles criteria variable and explanatory variable. When trying to estimate or extrapolate a future event based on information that is known, predictor variables are crucial. They aid in foreseeing the unforeseen. Compared to more well-known forms of variables, such as independent and dependent variables, this variable type is unique. Let's dissect these many sorts in the parts that follow.
Because both a predictive variable and an independent variable are used to establish a relationship, usually one to a dependent variable, they are comparable to each other. Experimentation can be used to ascertain whether an independent variable has an impact on a dependent variable.
Predictor variable, however, is different because they are only utilized to make predictions rather than determine final results. Here, independent variables are employed to establish causation, which is another significant distinction. Do independent variables actually affect outcomes rather than simply predicting them? In contrast to independent variables, predictor variables are not also subject to manipulation by the researcher.
