Each selected statistic is computed for each measure variable by values of Age category.Thefirst
column contains estimates of the average number of times per week that people of each category
engage in a particular type of activity. The confidence intervals for the means allow you to make
some interesting conclusions.
In terms of vigorous and moderate activities, 25–44-year-olds are less active than those 18–24
and 45–64, and 45–64-year-olds are less active than those 65 or older.
In terms of strength activity, 25–44-year-olds are less active than those 45–64, and 18–24 and
45–64-year-olds are less active than those 65 or older.
Summary
Using the Complex Samples Descriptives procedure, you have obtained statistics for the activity
levels of U.S. citizens.
Overall, Americans spend varying amounts of time at different types of activities.
When broken down by age, it roughly appears that post-collegiate Americans are initially less
active than they were while in school but become more conscientious about exercising as
they age.
Related Procedures
The Complex Samples Descriptives procedure is a useful tool for obtaining univariate descriptive
statistics of scale measures for observations obtained via a complex sampling design.
The Complex Samples Sampling Wizard is used to specify complex sampling design
specifications and obtain a sample. The sampling plan file created by the Sampling Wizard
contains a default analysis plan and can be specified in the Plan dialog box when you are
analyzing the sample obtained according to that plan.
The Complex Samples Analysis Preparation Wizard is used to set analysis specifications for
an existing complex sample. The analysis plan file created by the Sampling Wizard can be
specified in the Plan dialog box when you are analyzing the sample corresponding to that plan.
The Complex Samples Ratios procedure provides descriptive statistics for ratios of scale
measures.
The Complex Samples Frequencies procedure provides univariate descriptive statistics of
categorical variables.
