Hello,

I am doing my thesis and I use SPSS for the first time. Please help me even if my questions seem stupid.

First question.

I classified the age of the beginning of the symptoms in 5 intervals:

20 years or less.

From 21 to 30 years.

From 31 to 40 years.

From 41 to 50 years.

51 years or more.

In this case what is the variable type in SPSS. Is it scale or nominal or ordinal.

If I want to make Contingency table with the variable " Sex of the patient " to determine if 2 variables are linked, which statistical test should I use (Khi2 or correlation or other). Because I read on Web that the test khi2 is used only for 2 nominal variables.

2nd question.

I classified the time needed for diagnosis as follows:

less than 1 year.

1 year.

2 years.

3 years.

4 years.

5 years.

6 years.

8 years.

9 years.

10 years or more.

So in this case could I calculate the mean and how. I need an urgent answer.

thank you very much
