Answer 1

Key Points

Types of variables	Explanation
Extraneous variable	An extraneous variable is an uncontrolled variable that can have a significant effect on the unmanipulated variable, potentially leading to confounding results in an experiment. It is important to control for extraneous variables.
Independent variable	The independent variable is the variable that is deliberately manipulated or changed by the researcher in an experiment. It is the variable that is hypothesized to have an effect on the dependent variable.
Intervening variable	An intervening variable is a variable that comes between the independent variable and the dependent variable. It may mediate or explain the relationship between the two variables and is often related to the mechanism or process.
Dependent variable	The dependent variable is the variable that is measured or observed to determine the effect of the independent variable. It is the variable that is expected to be influenced or affected by the changes in the independent variable.

Hence the correct match is (a) - (iv), (b) - (iii), (c) - (i), (d) - (ii)
