How is the chi square independence test similar to the goodness of fit test how is it different?
With either test, you have a number of categories and for each you have an expected number of observations. The expected number is based either on the variable being independent of some other variable, or determined by some know (or hypothesised) distribution. You will also have a number of observations of the variable for each category. The test statistic is based on the observed and expected frequencies and has a chi-squared distribution.
The tests require the observations to come from independent, identically distributed variables.

When is chi-square tests for goodness of fit used?
Chi-Square Goodness-of-fit Test is used when you want to test if the sample observed follows an assumed theoretical distribution.
Is the chi-square goodness of fit a one-tailed test with the rejection region in the right tail?
true
Is the chi square of independence test a test a test of significance?
Yes.
What is the purpose of Chi Square Analysis?
Chi-square is mainly used for a goodness of fit test. This is a test designed to assess how well a set of observations agree with what might be expected from some hypothesised distribution.
Which figures would be similar to a 4 inch square?
Every square is. There are an infinite number of them.
When is the chi-test used?
There are many chi-squared tests. You may mean the chi-square goodness-of-fit test or chi-square test for independence. Here is what they are used for.A test of goodness of fit establishes if an observed frequency differs from a theoretical distribution.A test of independence looks at whether paired observations on two variables, expressed in a contingency table, are independent of each.
What is the definition of similar figures?
Similar figures are polygons with the same shape but a different size. eg: 5cm square compared to a 10cm square = similar figures. Same shape but different size.
Is a square and rectangle similar to a trapiziod?
Similar polygons have congruent angles and the same shape (but not necessarily the same size). Since the shape of a square and a rectangle is different from the shape of a trapezoid, they are not similar to it.
When is chi-square tests for goodness of fit used?
Chi-Square Goodness-of-fit Test is used when you want to test if the sample observed follows an assumed theoretical distribution.
Is a pie chart good for chi-square goodness of fit test?
Probably not.
A quadilateral with opposite sides parallel and congruent?
Square Square, rectangle (opposite sides are congruent and parralel), rhombus (similar to square but different angles although opposite angles are the same)
When is the chi-square goodness of fit a one-tailed test with the rejection region in the left tail?
Normally never! I suppose that it could be used to test if the goodness of fit is too good to be true!
Is the chi-square goodness of fit a one-tailed test with the rejection region in the right tail?
true
Can population percentage be used to calculate chi-square goodness of fit test?
No, it cannot be used to measure that.
Where is independence square located?
Cinema, Missouri
Which figure would be similar to a 4-inch square?
A square of any size would be similar.
Where is Monuments of Mustakillik?
It is not Monuments, it is big square, where Uzbekistan celebrates it big and national holidays in that square. It is located in Tashkent the capital of Uzbekistan, however, I guess, there might be more than one Mustakillik square. Because "Mistaqillik" means independence, so Mustaqillik square is Independence's Square
