You're probably used to the word "variable" in algebra. Letters like x and y are used in place of numbers. Twotypes of variables are used in statistics: Quantitative and categorical. Quantitative variables are numerical: counts, percents, or numbers. Categorical variables are descriptions of groups or things, like "breeds of dog" or "voting preference".
Examples of Quantitative Variables:- High school Grade Point Average.
- Number of pets owned.
- Bank account balance.
- Number of stars in a solar system.
- Average number of lottery tickets sold.
- How many cousins you have.
- The amount in your paycheck.
General rule: if you can add it, it's quantitative. For example, a G.P.A. of 3.3 and a G.P.A. of 4.0 can be added together (3.3 + 4.0 = 7.3), so that means it's quantitative.
Examples of Categorical Variables:- Class in college (freshman, sophomore, junior, senior).
- Party affiliation (Republican, Democrat, Independent).
- Type of pet owned (dog, cat, rodent, fish).
- Favorite author.
- Preferred airline.
- Hair color.
- Your race.
- Types of hats.
As a general rule, if you can't add something, then it's categorical. For example, you can't add cat + dog, or Republican + Democrat.
What else can I help you with?
Does quantitative research typically use independent and dependent variables?
Some times. At other times it uses mutually dependent variables (changes in each variable affect the other).
What are characteristics of variable?
Variables are characteristics or attributes that can take on different values or categories. They can be classified as qualitative (categorical) or quantitative (numerical). Qualitative variables describe qualities or characteristics, such as color or type, while quantitative variables represent measurable quantities, such as height or age. Additionally, variables can be independent or dependent, depending on whether they influence or are influenced by other variables in a study or experiment.
What does collinear in statistics?
Two or more explanatory variables are collinear when they have a linear relationship with each other. You are usually expected to remove at least one of the variables from your multiple regression analysis.
When should you use a time plot to display quantitative data?
Whenever you suspect that the passage of time is one of the factors influencing one or more of the other variables you are investigating.
What is a scatter plot description?
A scatter plot is a graphical representation that displays the relationship between two quantitative variables. Each point on the plot corresponds to an observation, with one variable plotted along the x-axis and the other along the y-axis. By visualizing the data points, scatter plots can reveal trends, correlations, or patterns, such as whether an increase in one variable corresponds to an increase or decrease in the other. They are commonly used in statistics and data analysis to explore potential associations between variables.
What data can be referred to things that can be counted?
A quantitative variable is numeric and therefore can be counted discretely or continuously. The other side of the spectrum is qualitative variables.
What are the classifications of quantitative techniques?
Quantitative techniques can be classified into two main categories: descriptive and inferential statistics. Descriptive statistics summarize and describe the features of a dataset, using measures such as mean, median, mode, and standard deviation. Inferential statistics, on the other hand, involve making predictions or inferences about a population based on a sample, utilizing methods like hypothesis testing, regression analysis, and confidence intervals. Additionally, quantitative techniques can be further divided into experimental and observational methods, depending on whether the researcher manipulates variables or observes them in their natural context.

What research is based on numerical measurements?
Quantitative research is based on numerical measurements, such as statistics, percentages, and other numerical data. This approach involves collecting and analyzing data to draw conclusions and make predictions about a particular phenomenon. Quantitative research often utilizes statistical tools and methods to examine relationships between variables and test hypotheses.
A correlation of zero between two quantitative variables means that?
It means there is no discernable relationship between the two variables. Knowing one variable does not give you any help in working out the other. They are independent of each other.
What are the types of bariables?
Variables can be categorized into several types, primarily including quantitative and qualitative variables. Quantitative variables are numerical and can be further divided into discrete (countable values) and continuous (infinite possible values within a range). Qualitative variables, on the other hand, represent categories or attributes and can be classified as nominal (unordered categories) or ordinal (ordered categories). Understanding these types helps in selecting appropriate statistical methods for analysis.

Difference between qualitative and quantitative variables?
A quantitative variable is a variable that can be measured by a number, usually on a ratio scale, but at least on an interval or ordinal scale, such that less and more can be measured and determined.EXAMPLE:CARS IN A CAR PARKA qualitative variable is also called a categorical variable. The items are different, but the difference is not a measure, such as square and round, hungry and fed. Statistically, these variables may be known as binomial or amenable to chi-square analysis.EXAMPLE:RED CARS IN A CAR PARK
What is the other variables of what dissolves more quickly salt or borax?
Examples: granulation, temperature, stirring, volume of liquid.
