What does it mean if the mean is doubled but the standard deviation is the same?
The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved.
In which of these does an experimenter want to prevent variation?
controlled variable
What is the variable k in a direct variation?
the slope
What is a variation that is the relationship between two variable quantities with a constant ratio?
Direct variation.
In which of these does a experimenter want to prevent variation?
controlled variable (A+)
How do you do a direct variation with an inverse variation problem?
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
What is Seasonal variation?
Variation in the values of a variable dependent upon the time of the year is seasonal variation. A variable having seasonal variation exhibits a pattern that repeats after exactly one year.
What is the difference direct variation and inverse variation?
Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .

The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved.
In which of these does an experimenter want to prevent variation?
controlled variable
What is directly variation?
A variable y is said to be in direct variation with a variable x if there is a constant c (>0) such that y = c*x. c is called the constant of direct variation or proportionality.
What is the variable k in a direct variation?
the slope
What is direct square variation?
A variable, Y, is in direct square variation with a variable, X, if Y = kX2 where k is some (non-zero) constant.
What is a variation that is the relationship between two variable quantities with a constant ratio?
Direct variation.
Which variable does a experimenter want to prevent variation?
The variable that the experimenter wants to prevent variation in is the independent variable. This is the variable that is intentionally changed or manipulated by the experimenter to see its effect on the dependent variable. By controlling the independent variable and keeping it constant, the experimenter can ensure that any changes in the dependent variable are a result of the manipulation of the independent variable.
In which of these does a experimenter want to prevent variation?
controlled variable (A+)
Can VARIATION be abbriviated?
Of course it can be abbreviated Var. But then it might be confused with Variable.
