I do have a question, given are 12 observed values (see SPSS outprint in attachment)

4,1

4,3

4,6

4,9

5,0

5,1

5,1

5,6

5,6

5,6

6,0

6,4

I have no idea how to calculate the expected values for this K-S test. Can someone help me a bit, this is a test for the normal distribution.

The result is 0,1369

btw:

Just to clarify......the Java right here is solo...so it's Solo/Java

Greetings,

Java/solo

I have a issue about two-tailed inverse of the student`s t-distribution. I am trying to use calculation for two-tailed inverse of the student`s t-distribution function presented by Excel functions like =TINV(probability, deg_freedom).

Where:

alpha (a)= 0.05

degree of freedom (df)= 1221

p (two-tailed)= 0.0000408831

Next, just do calculate for two-tailed INVERSE of the student`s t-distribution using Excel formula as below;

=TINV(probability, deg_freedom)

=TINV(0.0000408831, 1221)

= 4.117456798

Resulted: 4.117456798

Could you show me a manual calculation step by step for TINV function.

Appreciate your helps in advance. Thanks

I have a survey that collects data from each respondent on gender and also on attitudes.

We don't know in advance how many men or women will be identified.

We then ask attitudinal questions of each and wish to test for differences between the male and female groups.

It seemed clear that the base for each group (number men, number of women in total) was itself random and that this needed to be taken into account when estimating the variance of estimated proportions calculated on each gender group.

Also I thought there will be a negative correlation between the size of the male and female groups. Is there a way of computing the variance in this scenario?

Best wishes,
