Variables for which their central characteristics is that they can be measured along a continuum and they have a numerical value
Ratio
Interval
Dichotomous
Nominal
This is sometimes called an experimental or predictor variable.
Independent Variable
Dependent Variable
Correlation
Quasi-experimental
This refers to nominal variables which have only two categories or levels
Ratio
Interval
Dichotomous
Nominal
In your own understanding, what is the aim of dependent variable in writing research problem?
The aim is to manipulate a dependent variable(s) and then examine the effect that this change has on an independent variable(s)
The aim is to manipulate an independent variable(s) and then examine the effect that this change has on a dependent variable(s)
The aim is to manipulate a profile variable(s) and then examine the effect that this change has on a dependent variable(s)
The aim is to manipulate an independent variable(s) and then examine the effect that this change has on a correlational variable(s)
This variable acts as the cause in that they precede, influence, and predict the dependent variable
Dependent
Independent
Extraneous
Confounding
As a researcher, you must know about continuous variable. One of your groupmates asks you to explain to them what the use of continuous variable is, your BEST response will be:
Measured on a scale that theoretically can take on an infinite number of values
Interval variables, but with the added condition that 0 (zero) of the measurement indicates that there is none of that variable
Nominal variables which have only two categories or levels.
Variables for which their central characteristic is that they cannot be measured along a continuum and they have a numerical value
Which of the following statement is TRUE about nominal variable?
Interval variables, but with the added condition that 0 (zero) of the measurement indicates that there is none of that variable
Measured on a scale that theoretically can take on an infinite number of values
Variables for which their central characteristic is that they can be measured along a continuum and they have a numerical value
Variables that have two or more categories, but which do not have an intrinsic order
Teacher Rhizon asks you to explain about ratio your BEST answer will be:
Interval variables, but with the added condition that 0 (zero) of the measurement indicates that there is none of that variable
Measured on a scale that theoretically can take on an infinite number of values
Nominal variables which have only two categories or levels
Variables for which their central characteristic is that they can be measured along a continuum and they have a numerical value
Which of the following is an example of Discrete Variable
Distance
Volume
Number of different tree species in a forest
Age
Which of the following is an example of nominal variable
Colors
Finishing place in a race
Level of Satisfaction
Rating scale responses in a survey

Variables with values that describe a quality or characteristic of a data unit
Numeric
Categorical
Experimental
Non-experimental
Statement A: Nominal variable serve the purpose of classification and ranking

You want to figure out which brand of microwave popcorn pops the most kernels so you can get the most value for your money. You test different brands of popcorn to see which bag pops the most popcorn kernels.
Independent: Brand of microwave popcorn
Dependent: Brand of popcorn bag
Independent: Number of kernel popped
Extraneous: Number of kernel popped
You're interested in how rising sea temperatures impact algae life, so you design an experiment that measures the number of algae in a sample of water taken from a specific ocean site under varying temperatures.
Independent: The number of algae in the sample
Confounding: Sea temperature
Dependent: The number of algae in the sample
Extraneous: Sea temperature
The impact of learning format/teaching style on exam performance.
Independent: exam performance
Dependent: learning format/teaching style
Extraneous: quality of lecturer vs. seminars
Confounding: student tiredness

How much the participants weighed before the study
How much the participants weighed during the study
How much participants liked their meals
None of these
