- Q1This type of variable is often considered as the effect in a cause-and-effect relationship. Which variable is described in the previous sentence?Continuous variableIndependent variableDependent variableControl variable30s
- Q2Which of the following statement is INCORRECT?Defining operationally means specifying how variables are measured.Two variables have a linear relationship when they are proportional to each other at a constant value.Independent variables the ones that are observed and measured to determine the effects of the dependent variable.Anything that varies can be treated as a variable.30s
- Q3When do variables exhibit a non-linear relationship?None of the choicesIf the constant increase / decrease in one of the variables results to varying increase / decrease in other variables.If the constant increase / decrease in one of the variables results to constant increase / decrease in other variables.If there is no significant pattern between the variables.30s
- Q4Which type of variable relationship does the figure show?Negative linear relationshipUnrelatedPositive non-linear relationshipNegative non-linear relationship30s
- Q5What relationship statement could be made from the figure shown in the previous item?As the temperature decreases, the time constantly decreases.As the temperature increases, the time constantly increases.As the time increases, the temperature constantly increases.As the time increases, the temperature constantly decreases.30s

- Q8This type of variable is often considered as the cause in a cause-and-effect relationship. Which is type of variable is described above?Discrete variableIndependent variableExtraneous variableDependent variable30s
- Q9Which of the following statements is CORRECT?Extraneous variables always affect the results of a science experiment.In a study where one variable causes a change in another, the dependent variable is the cause.We practice an integrated process skill by describing relationships between variables.A non-linear relationship exists when two quantities are proportional to each other at a constant value.30s
