Data analysis help please!

#1
Hi,

I'm an SPSS and stats newbie. Could anyone please show me how to create a table like the one below and filter the data according to the requirements below?

Thanks!

Variable X | Variable Y | Variable Z
Mean | | |
Median | | |
Min | | |
Max | | |


I also need this data filtered by the sum values in selected variable columns.
1. No filter
2. Filtered by sum of Variable B + Variable C > 90 (in each row)
3. Filtered by sum of Variable B + Variable C > 90 (in each row)
4. Compare mean and median of filter 2 with mean and median of filter 3 to determine if there is a significant difference

I've attached the data and modified it a little. So basically I want:

The table in the picture attached plus:
1. No filter
2. Limit analysis to only include rows where Variable P ≥ 90
3. Limit analysis to only include rows where Variable Q ≥ 90
4. Compare mean and median of filter 2 with mean and median of filter 3 to determine if there is a significant difference

Thanks!
