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.

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 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 are examples variables in a equation?
Y = 2X Variables are X and Y If X = 2, then Y = 4 If X = 3, then Y = 6 and so forth. If you vary one then he other changes. Their values are variable.
What is the relationship of statistics to the other field?
Statistics and Logic - the political theorist must possess a broad scientific background and a knowledge of current political problems, and he must employ scientific methods in gathering and evaluating data and in drawing conclusions. These involve a proper application of statistical procedures for the quantitative measurement of social phenomena and of logical procedures for the analysis of reasoning.
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.
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 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 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.
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.
What is a zero order table in statistics?
In statistics, a zero order table is a simple frequency distribution table that displays the counts or frequencies of each unique value in a dataset without considering any other variables. It provides a basic summary of the distribution of values in the dataset.
What is sensitive price index?
(Mathematics & Measurements / Statistics) a numerical scale by means of which variables, such as levels of the cost of living, can be compared with each other or with some base number
What are examples variables in a equation?
Y = 2X Variables are X and Y If X = 2, then Y = 4 If X = 3, then Y = 6 and so forth. If you vary one then he other changes. Their values are variable.
What is standardized raw data?
Standardization of raw data is the process of making its variables proportionate to each other. In statistics, it is often achieved by subtracting the mean from values and then dividing them by their Standard Deviation.
