Question

Rejecting the null hypothesis that the population slope is equal to zero or no relationship and concluding that the relationship between x and y is significant does not enable one to conclude that a cause-and-effect relationship is present between x and y. Explain why.

Answer 1

Anso Rejecting the Slope is equal to tero null hypothesis (ha that the population no relationship and concluding that the relationship blue and y' is significant that and effect relationship is prevent one to conclude does not enable between yand from cause and The cause and effect relationship cannot be served the significant slope of regression equation. because tegression is about correlation relation ship between the variables where as the cause etrect relationship is known by studying several other parameters of context, qualities measure, confounding variables effect relationship is beyond quantifre dda. Peqression equation is obtained using quantitive data and is contined to such data. so. it the null hypothesis hol is rejected then the conclation relationship between the variables is significant but there is nothing to say about cause and extent relationship. Moreover any unrelated variables using can have significant correlation and it does not charge in one variable is causing the charge The and looking important here. means in the other variable, for the confounding context eticat

The cause and effect Telationship is beyond the data. The quantitative data is one of the parameters to find and effect relationship between the variables, but not the entire things. cause
