The Regression analysis test is a statistical test that can be used in measuring the gadget usage of children at home during quarantine:

• Regression analysis: A statistical test that helps to estimate the values of one variable from the known or given values of other variables on the basis of an average mathematical relationship. In this test, if two variables are chosen ( n, m ) and one variable (n) is influenced by the second variable (m), then both the variables are termed as dependent variable (n) and independent variable (m) respectively.
• The Quasi-experimental design approach is used in the given test.

• Quasi-experimental design: It is a research tool/ design that is used to define, obtain and establish the cause-effect relationship between two chosen variables which includes an independent variable and a dependent variable.
• Here, home quarantine is the independent variable, while usage of gadgets during quarantine is the dependent variable.
