Measurement and prediction I (levels of measurement, sources of error, probability)

Activity 1 – Work in pairs (or in a trio if there is one person left without a partner) as follows: in surname alphabetical order the first and second person pair up, the third and fourth and so on.  Between you, compile a list of examples that fit the four different levels of measurement and try to find 5 examples of each.  Once you are happy with your list, post it on the discussion board for comment by other members of the group and be prepared to comment on others’ lists.


Activity 2 – Reflect in a blog entry what you have learned about measurement and prediction and what, if anything, was new to you and what you learned.  See if you can find some other interesting and informative links or materials that you can include in your entry and then share the link to your blog the group via the discussion board.

Introduction to module (aims & objectives, installing SPSS, setting up a blog, aims of the assessment)

Activity 1 – Once you have set up your blog make a short entry, titled ‘About me’, of 100-250 words telling the other members of the group something about yourself—personal, professional, hobbies—and what you hope to get out of participating in the module.  If you can include a photograph that is good but not compulsory.  Once you have done that please paste the URL for the blog into a message and post it on the discussion board.

Activity 2 – Install SPSS on your computer; once you have installed it successfully please let the other members of the group know on the discussion board and please be willing to advise other members of the group who may be having problems with this.  If you are having problems, please ask other members of the group to help.
