mean median mode st.dev

[behnaz shirazi-2]

Hello Dear All:

Do you have any idea how I can have mean median mode st.dev for a variable
using multiple data set
..I need to compare these values.I am using add files but I don't know how I
can get mean median mode and etc.. for a variable.


Thank you
Behnaz

Behnaz,

Your question is hard to understand and I don't know if this will help.

As I understand you, you have multiple datasets. Apparently each dataset has
the same variable in it. You want standard descriptive statistics for that
variable. You say you need to compare 'these values'. Are you aware that
statistical comparisons can be done for means or medians but not modes or
standard deviations (SD)? (Other readers: Am I correct that spss has no
comparisons for modes or SDs??) You have done an Add files. Do you have a
variable that identifies each component dataset once they have been added?
If not, you should have one. Look at the In subcommand of the Add files
command. You specify an 'in' variable for each dataset. You can then use
those variables to make a new variable that identifies each dataset. Or, you
could add a new variable to each component dataset before the add files. The
variable added has the same name in each component dataset but has a value
of 1 for the first dataset, 2 for the second, etc.

Once the files have been added you can use the Split files command to
compute descriptives statistics for each dataset. Medians can be compared
using the Median subcommand of the Npar procedure and means can be compared
using, for instanct, oneway.

Does this even get close to what you want?

Thank you Gene.That was very helpful I appreciated that.Just one more thing
I need to split them by gender or sex also.There are some unreported or
missing values.How can I get rid of them?


SORT CASES BY DISTINCT SEX.
SPLIT FILES BY DISTINCT SEX.
FREQUENCIES ageyr/STATISTICS MEAN MEDIAN MODE STDDEV.
SPLIT FILES OFF.

Best Regards,
Behnaz
