What are the 5 types of variables?
There are six common variable types:DEPENDENT VARIABLES.INDEPENDENT VARIABLES.INTERVENING VARIABLES.MODERATOR VARIABLES.CONTROL VARIABLES.EXTRANEOUS VARIABLES..
Is name a categorical variable?
Categorical variables take on values that are names or labels. The color of a ball (e.g., red, green, blue) or the breed of a dog (e.g., collie, shepherd, terrier) would be examples of categorical variables.
Is Money discrete or continuous?
A continuous distribution should have an infinite number of values between $0.00 and $0.01. Money does not have this property – there is always an indivisible unit of smallest currency. And as such, money is a discrete quantity.
Is the floor area of a kitchen discrete or continuous?
Then, the floor area of a kitchen is a continuous random variable. B. Quantity is a discrete unit. Then, the number of bacteria in a particular cubic centimeter of drinking water is a discrete random variable.
How do you identify categorical variables?
3 Answers. You could say that some variables are categorical or treat them as categorical by the length of their unique values. For instance if a variable has only unique values [-2,4,56] you could treat this variable as categorical. Every unique value in every variable treated as categorical will create a new column.
Is weight continuous or discrete?
Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable. Foot length is also a continuous random variable. Continuous random variables are often measurements, such as weight or length.
Is IQ discrete or continuous?
When you’re ready, check your answer below. IQ – discrete. IQ scores are always integers – 100, 110, 180, etc. ACT – discrete.
What kind of variable is gender?
nominal variableA nominal variable (as in “noun”) cannot be counted. For example, gender is a nominal variable having two categories (male and female) and there is no intrinsic ordering to the categories. You can assign a numerical value (e.g “Male” = 1, “Female” = 2) but you cannot rank the data from highest to lowest.
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.
Is gender a categorical variable?
For example, gender is a categorical data because it can be categorized into male and female according to some unique qualities possessed by each gender.
Is gender an independent variable?
Although social class, religion, gender, ethnicity and age are often treated as independent variables (e.g., factors, forces, structures) and invoked as causal explanations for various outcomes, this paper approaches these constructs in more distinctive, humanly-engaged terms.
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 hours of sleep discrete or continuous?
Amount of sleep is a variable. 3, 5, 9 hours of sleep are different values for that variable. Variables can be continuous or discrete. Question: Are these variables discrete or continuous?…Frequency distribution table:Score (X)Frequency (f)(Hours)(Number of people with this score)3142561 more row
Is age continuous or discrete?
We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous. However, in everyday appliances, all values under 6 years and above 5 years are called 5 years old. So we use age usually as a discrete variable.
Is gender a quantitative variable?
Typically, a variable can describe either a quantitative or qualitative characteristic of an individual. Examples of quantitative characteristics are age, BMI, creatinine, and time from birth to death. Examples of qualitative characteristics are gender, race, genotype and vital status.
What is discrete continuous and qualitative data?
Qualitative Data are not numbers. They may include favorite foods; religions; ethnicities; etc.. Discrete Data are numbers that may take on specific, separated values. … Continuous Data are numbers that may take on all sorts of decimal or fractional values.
Is grouped data continuous or discrete?
Continuous data is usually recorded as grouped data so is usually represented by histograms or cumulative frequency graphs. Sometimes discrete data is also recorded in groups to make calculations quicker.
What are 3 types of variables?
There are three main variables: independent variable, dependent variable and controlled variables.

Is heart rate a discrete or continuous variable?
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.
Is marital status discrete or continuous?
Continuous a. Discrete data has distinct set of values, which are countable and belonging to whole numbers set e.g. The marital status of a person is a nominal qualitative variable to which a numerical value can not be assigned.
