Probability Crosstabulation Method

In summary, the speaker is seeking help with understanding the tabulation method for computing probabilities, as introduced by their professor. They are unable to code an array or table in latex and have attached an image of the problem using imageshack. The speaker is also disappointed that their probability book does not cover this method and is asking for references or examples to better understand the concept.

I don't really understand the tabulation method of computing probabilites that my professor has introduced us to, so I'm trying to get a little help on the following problem. I don' t know how to code an array or table in latex so to make my post look better I used an attachment. and use imageshack to host the image I'm really sorry about that.

I really don't know where to begin I just need a push or two in the right direction. My probability book does not cover this method so all I have for a reference is my class notes

Can someone just point me to a webpage or other source that has a few examples of this kind of crosstabulation?
 

FAQ: Probability Crosstabulation Method

What is probability crosstabulation method?

The probability crosstabulation method is a statistical technique used to analyze the relationship between two categorical variables. It involves creating a contingency table, also known as a crosstab, which displays the frequencies of each combination of values for the two variables.

How is the crosstabulation table created?

The crosstabulation table is created by listing the categories of one variable along one axis and the categories of the other variable along the other axis. The frequency of each combination of categories is then filled in the corresponding cell.

What is the purpose of using probability crosstabulation method?

The purpose of using probability crosstabulation method is to identify any patterns or relationships between the two variables. It allows for a visual representation of the data, making it easier to interpret and draw conclusions.

How is probability calculated in crosstabulation method?

In crosstabulation method, probability is calculated by dividing the frequency of a specific combination of categories by the total number of observations. This gives the likelihood or chance of that particular combination occurring.

What is the difference between crosstabulation and correlation?

Crosstabulation is a descriptive method that shows the relationship between two categorical variables, while correlation is a measure of the strength and direction of the relationship between two continuous variables. Crosstabulation tells us if there is a relationship between variables, while correlation tells us how strong that relationship is.
