If you need to collect a lot of data or want to encourage pupils to consider how data collection can be carried out then Survey Monkey is the website for you.
A basic membership is free: it allows you to create and carry out a 10 question survey online.
A paid for membership allows you to customise your survey and download the results. The survey can be longer than 10 questions.
I’ve introduced SurveyMonkey to the staff where I teach. We have used it to survey pupils on their opinions of feedback/marking in books, pupil experience of IT, staff implementation of IT, feedback from CPD sessions, data collection for Masters research and even collecting food orders for parents evening!
In class, you could also use it to start a discussion on bias, types of question, how appropriate different charts are and why companies use sites like SurveyMonkey to collect consumer data.
