  1. Secondary data/information

  2. Secondary data can be: science explanations, diagrams, tables of results, graphs • Fundamentals of waves Seeing, hearing, feeling warmth, surfing, tuning the radio, using a cellphone – these and many more activities involve waves. But what is a wave? In this article, we get to grips with the different kinds of waves and look at the key characteristics of all waves – their wavelength, period, frequency, speed and amplitude. These concepts are important for describing waves of all kinds.

  3. Places you can find secondary data: • Internet • Textbook • Pupils in your group doing the same/different experiments • Calculating predicted results from formulae • Given by the exam board

  4. If you are trying to find tables of results or graphs.. • What is my independent variable? • What is my dependent variable?

  5. Only use sources that you understand.

  6. Make a numbered bibliography listing all your sources. References [1] Geiver L. and Jessen Holly.

  7. Comparing primary and secondary data • Primary data = results you have collected yourself • Secondary data = information you have researched (Hint: It can be easier to compare sources if they are both graphs – sometimes you may want to plot a graph from the secondary data)

  8. Check…… • What are the similarities/differences? • Do they cover the same range? • Are they measure in the same units? • How many different measurements are there? • Are there any repeats? • Do they have the same trends? • Do they give the same conclusion? (Are there any other detailed differences/similarities?) e.g gradients, (0,0)
