Treatment Variables A treatment variable is any variable whose effect on the data is to be studied as part of the objectives of the experiment.
What is a treatment variable in research?
Treatment. In an experiment, the factor (also called an independent variable) is an explanatory variable manipulated by the experimenter. Each factor has two or more levels, i.e., different values of the factor. Combinations of factor levels are called treatments. The table below shows independent variables, factors, levels, and treatments for a hypothetical experiment.

the specific condition to which a group or participant is exposed in a study or experiment. For example, in a design employing four groups, each of which is exposed to a different dosage of a particular drug, each dosage amount represents a level of the treatment factor.
Is treatment a dependent variable?
When a researcher gives an active medication to one group of people and a placebo, or inactive medication, to another group of people, the independent variable is the medication treatment. Each person's response to the active medication or placebo is called the dependent variable.
Is gender nominal or dichotomous?
Dichotomous variables are nominal variables which have only two categories or levels. For example, if we were looking at gender, we would most probably categorize somebody as either "male" or "female". This is an example of a dichotomous variable (and also a nominal variable).

How do you identify a controlled variable?
Control variables = the type of plant used, the amount of fertiliser given, the time given to grow. And all other conditions kept the same between each plant e.g. the amount of water each plant receives, the temperature of the room, the amount of sunlight etc.
What is statistical treatment?
‘Statistical treatment’ is when you apply a statistical method to a data set to draw meaning from it . Statistical treatment can be either descriptive statistics, which describes the relationship between variables in a population, or inferential statistics, which tests a hypothesis by making inferences from the collected data.
Why do you need to know statistical treatment?
This is because designing experiments and collecting data are only a small part of conducting research.
What are the two types of errors in an experiment?
No matter how careful we are, all experiments are subject to inaccuracies resulting from two types of errors: systematic errors and random errors. Systematic errors are errors associated with either the equipment being used to collect the data or with the method in which they are used.
How many words are in a PhD thesis?
In the UK, a dissertation, usually around 20,000 words is written by undergraduate and Master’s students, whilst a thesis, around 80,000 words, is written as part of a PhD.
What is variable in statistics?
Published on November 21, 2019 by Rebecca Bevans. Revised on March 2, 2021. In statistical research, a variable is defined as an attribute of an object of study. Choosing which variables to measure is central to good experimental design. Example.
What are the variables that represent the outcome of the experiment?
Variables that represent the outcome of the experiment. Any measurement of plant health and growth: in this case, plant height and wilting. Variables that are held constant throughout the experiment. The temperature and light in the room the plants are kept in, and the volume of water given to each plant.
How to tell if a variable is independent or dependent?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.
What is the difference between categorical and quantitative variables?
What is the difference between quantitative and categorical variables? Quantitative variables are any variables where the data represent amounts ( e.g. height, weight, or age). Categorical variables are any variables where the data represent groups.
What is a confounding variable?
A confounding variable, also called a confounder or confounding factor, is a third variable in a study examining a potential cause-and-effect relationship. A confounding variable is related to both the supposed cause and the supposed effect of the study.
What are independent variables?
Independent variables (aka treatment variables) Variables you manipulate in order to affect the outcome of an experiment. The amount of salt added to each plant’s water. Dependent variables (aka response variables) Variables that represent the outcome of the experiment.

There are three types of categorical variables: binary, nominal, and ordinal variables.
What is a variable?
A variable is an attribute that describes a person, place, thing, or idea. The value of the variable can "vary" from one entity to another. For example, a person's hair color is a potential variable, which could have the value of "blond" for one person and "brunette" for another.
What is a quantitative variable?
Quantitative variables can be further classified as discrete or continuous. If a variable can take on any value between its minimum value and its maximum value, it is called a continuous variable; otherwise, it is called a discrete variable.

Introduction to Statistical Treatment in Research
- Every research student, regardless of whether they are a biologist, computer scientist or psychologist, must have a basic understanding of statistical treatment if their study is to be reliable. This is because designing experiments and collecting data are only a small part of conducting research. The other components, which are often not so well understood by new res…
What Is Statistical Treatment of Data?
- Statistical treatment of data is when you apply some form of statistical method to a data set to transform it from a group of meaningless numbers into meaningful output. Statistical treatment of data involves the use of statistical methods such as: 1. mean, 2. mode, 3. median, 4. regression, 5. conditional probability, 6. sampling, 7. standard deviation and 8. distribution range…
Statistical Treatment Example – Quantitative Research
- For a statistical treatment of data example, consider a medical study that is investigating the effect of a drug on the human population. As the drug can affect different people in different ways based on parameters such as gender, age and race, the researchers would want to group the data into different subgroups based on these parameters to determine how each one affects the effe…
