How do you find degrees of freedom for a chi-squared test?
The degrees of freedom for a chi-squarded test is k-1, where k equals the number of categories for the test.
How can you determine whether two variables x and y for a real life situation are correlated?
You calculate a correlation coefficient and test to see if it is statistically different from 0.
Which is a perfect square number 10 50 1600 124 or 200?
1600 Why r u trying to cheat at the iq test?
When can you not invert a matrix?
If it is not a square matrix. You cannot invert a square matrix if it is singular. That means that at least one of the rows of the matrix can be expressed as a linear combination of the other rows. A simple test is that a matrix cannot be inverted if its determinant is zero.
The square root of -1 is an number?
The Square root of -1 is an _________ number Possible answers: imaginary, infinite, indefinite *You may be taking the same [url=http://intelligence-test.net/part_4/?m=3]online test[/url] that I am :D * * * * * And the answer is ... IMAGINARY!
What is the critical value of chi-square with a significant level of equals 0.05?
Critical values of a chi-square test depend on the degrees of freedom.
How do you find degrees of freedom for a chi-squared test?
The degrees of freedom for a chi-squarded test is k-1, where k equals the number of categories for the test.
Why there is no degrees of freedom in Z test?
so
In a two-way contingency table with four rows and four columns the appropriate degrees of freedom for the chi-square test statistic is?
The degrees of freedom for any contingency table can be calculated simply by the formula (r-1)x(c-1) where r= the number of rows and c= the number of columns. Thus for a contingency table with four rows and four columns the degrees of freedom are 3x3 = 9.
What is the table value of 5 percent significant level in f test?
It depends on the degrees of freedom for the f-test.
How do you find the degrees of freedom when using the t distribution to estimate or test the mean of a sample from a single population?
If the sample consisted of n observations, then the degrees of freedom is (n-1).
Why is it impossible to compute a T statistic for a sample that has only one score?
A T test is used to find the probability of a scenario given a specific average and the number of degrees of freedom. You are free to use as few degrees of freedom as you wish, but you must have at least 1 degree of freedom. The formula to find the degrees of freedom is "n-1" or the population sample size minus 1. The minus 1 is because of the fact that the first n is not a degree of freedom because it is not an independent data source from the original, as it is the original. Degrees of freedom are another way of saying, "Additional data sources after the first". A T test requires there be at least 1 degree of freedom, so there is no variability to test for.
How do you find degrees of freedom for a chi squared test?
(r-1)x(c-1)
What values are specified by the null hypothesis for the chi square test for goodness or fit?
The value specified is usually the maximum value that the test statistic can take for a given level of statistical significance when the null hypothesis is true. This value will depend on the parameter of the chi-square distribution which is also known as its degrees of freedom.The value specified is usually the maximum value that the test statistic can take for a given level of statistical significance when the null hypothesis is true.

Can population percentage be used to calculate chi-square goodness of fit test?
No, it cannot be used to measure that.
How do you use the F Test to find the sample size for two sets of data?
The data sets determine the degrees of freedom for the F-test, nit the other way around!
The s2 statistic is used to test to test whether the assumption of normality is reasonable for a given population distribution The sample consists of 5000 observations and is divided into 6 category?
The s2 statistic is used to test to test whether the assumption of normality is reasonable for a given population distribution. The sample consists of 5000 observations and is divided into 6 categories (intervals). The degrees of freedom for the chi-square statistic is:
