What is x-bar in statistics?
The numerical average of a set of data is called x-bar. This is the sum of all values divided by the number of values.
Where is point of intersection of two regression lines?
The means of the two variable, (x-bar, y-bar)
How do you get the value of y intercept in least squares method?
To find the y-intercept, you need to calculate the gradient, b. Then a, the y-intercept, satisfies the equationy-bar = a + b*x-barwhere x-bar and y-bar are the means of the two variables.
How are statistics comparisons shown on bars or graphs?
error bar can be drawn for statistical comparison of bars and graphs.
What does mu mean in statistics?
Usually mu is the symbol for the mean of a probability distribution. It is sometimes used as the average of a dataset (also called the mean of the dataset), although I prefer to use "x bar".
What is the formula for x-bar in statistics?

What is the formula to find the x-bar in statistics?
_x?That's the average.sum of all x divided by nx
Where is point of intersection of two regression lines?

Are Greek letters used for statistics or for parameters?
Greek letters are used for population parameters. Eg: µ is the population mean English letters are used for sample statistics. Eg: x-bar is the sample mean
What is the symbol for mean difference in statistics?
d bar, d with a bar over it
What is the symbol for population mean in statistics?
μ is the symbol for the population mean in statistics. fyi and related but not necessary for the above answer: the sample mean is , enunciated by saying "x" bar. hope this helped. Citation : http://en.wikipedia.org/wiki/Arithmetic_mean

What is numeric x in statistics?
In statistics, letter such as; a,..x..,z, is a variable used to represent an unknown value.
How do you get the value of y intercept in least squares method?
To find the y-intercept, you need to calculate the gradient, b. Then a, the y-intercept, satisfies the equationy-bar = a + b*x-barwhere x-bar and y-bar are the means of the two variables.
Can x-x be a binomial expression?
if the bar between the x's means multiply... x2 is a binomial because if you have an x squared this indicates that... x2 + 0x + 0 which is a binomial expression
