What is the meaning of quantitative variables?
They are variables that can take quantitative - as opposed to qualitative values. For example, the colour of peoples' eyes is a qualitative variable, but their age or shoe size are quantitative variables.
What is The measure of the relationship between two variables?
correlation * * * * * Only if the relationship is linear. For example, the correlataion between y and x when y = x2 is zero. But a very strong relationship between the two variables.
What is co-variance?
Covariance is a measure of how much two variables change together.If one variable changes how much will the other change?Example people's length and weight change together (within certain limits) taller people are in general heavier than shorter people. These two variables have great covariance.Whereas eye color has little relationship to height. those two variables have small (or no) covariance.
3 types of variables?
controlled,manipulated,responding variables
What is a variable in QBASIC?
Variables in Qbasic are divided into two groups. There are numerical variables and string variables. This is how you would use a numerical variable: CLS INPUT "Enter your first number"; num1 INPUT "Enter your second number"; num2 num3 = num1 * num2 CLS PRINT "The product of the two numbers is"; num3 END This example just has the user input 2 variables (num1 and num2) and store them as numerical variables. Num3 is defined by multiplying the two user-imputed variables. The text displayed with PRINT contains normal text with a semi colon to display the result. This is a string variable example: CLS INPUT "What is my name?"; name$ PRINT "Hi I'm"; name$ END Instead of inputting just the variable name, you add a dollar sign to signify that it's a string variable. String variables contain letters rather than numbers. For string variables, you simply put the $ after the variable name every time it's used. Other than that, it's much like a numerical variable. That's a basic outline of how the variables work. Manipulating the string variables is a different story.
What is a mathematical phrase that can include numbers variable and operational symbols?
An algebraic expression is a mathematical phrase that includes numbers, variables, and operational symbols.
What is a mathematical phrase that contains numbers and operational signs?
A mathematical phrase that contains numbers and operational signs is called an "expression." An expression can include numbers, variables, and operations such as addition, subtraction, multiplication, and division. For example, (3x + 5 - 2) is an expression that combines numbers and operational signs. Unlike equations, expressions do not contain an equality sign.
Operational variable in science?
An operational definition of a variable is that which defines a variable in terms of operations that are used to measure it. This allows different investigators to perform the same or similar experiments when investigating a phenomenon. For example, a score on a standardized IQ (i.e., intelligence quotient) test might be the operational definition of the variable "intelligence."
What is an Example of two independent variables?
Variables are symbols that replace unknown numbers. Variables are often letters. For example: 5*x=10 7*6=y Here "x" and "y" are the variables.
Can you give me an example of operational feasibility?
No.
