Please read my update at the end of this post.

Statistics::Basic is not a core module and is not part of the Strawberry Perl distribution. Normally to install this open a command prompt and type:

cpan Statistics::Basic
[download]

This should retrieve and install Statistics::Basic and its dependencies.However you'll need to patch it (because of this bug on Number::Format, a prerequisite) like so, again from the command line:

cpan
cpan> look Number::Format

Running look for module 'Number::Format'

Trying to open a subshell in the build directory...

At this point save this file to the path displayed in your prompt (in my example it's D:\perl\cpan\build\Number-Format-1.73-L6b3hX, it'll be slightly different for you). Then back at the command prompt:

At this stage you manually patched and installed Number::Format, now your goal was Statistics::Basic, we drop back to the cpan shell and install it as normal:

D:\perl\cpan\build\Number-Format-1.73-L6b3hX>exit

cpan> install Statistics::Basic
[download]

All going well cpan will now install the module. Let us know if you have problems.

Update: This isn't a stupid question, not knowing how to do this doesn't make you dumb. Nobody was born knowing how to do this. Take a look at PerlMonks for the Absolute Beginner from the Tutorials section, along with How do I post a question effectively?.
