Is number of students discrete or continuous?
Discrete vs continuous data
| Discrete data | Continuous data |
|---|---|
| Some common examples of discrete data are the number of students, the number of children, the shoe size, and so on | Some common examples of continuous data are height, weight, length, time, temperature, age, and so on |
Is salary discrete or continuous?
Glossary: Discrete Data For example, salary levels and performance classifications are discrete variables, whereas height and weight are continuous variables.
Is gender continuous or discrete?

How do you know if something is discrete or continuous?
A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A random variable is a variable whose value is a numerical outcome of a random phenomenon. A discrete random variable X has a countable number of possible values.
Is heart beats per minute discrete or continuous?
Variables such as heart rate, platelet count and respiration rate are in fact discrete yet are considered continuous because of large number of possible values. Only those variables which can take a small number of values, say, less than 10, are generally considered discrete.
Can gender be a continuous variable?
Gender can be a continuous variable, not just a categorical one: Comment on Hyde, Bigler, Joel, Tate, and van Anders (2019)
Is birth years discrete or continuous?
Age is, technically, continuous and ratio. A person’s age does, after all, have a meaningful zero point (birth) and is continuous if you measure it precisely enough. It is meaningful to say that someone (or something) is 7.28 year old.
Is gender a continuous data?
continuous data. Discrete data: when the variable is restricted to specific defined values. For example, “male” or “female” are categorical discrete data values. Continuous data: when the variable is unrestricted and can have any value from a potentially infinite range, eg.
Which type of variable is gender?
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).
What will be kept the same control in each test?
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
What are the five steps of the scientific method in order from first to last?
The scientific method has five basic steps, plus one feedback step:
- Make an observation.
- Ask a question.
- Form a hypothesis, or testable explanation.
- Make a prediction based on the hypothesis.
- Test the prediction.
- Iterate: use the results to make new hypotheses or predictions.
