The analysis of the data involves responding to the questions above. These questions help you to evaluate your guesses, and assess whether the data collected is '''valid '''(ie. whether it can actually answer the enquiry questions) or '''reliable '''(ie. whether the data comes from a rigorous and trustworthy method of data collection). If you do not think the data fulfills the qualities of validity and reliability, then you should immediately highlight the problem and try to find out why this could have happened. It may be the case that you need to to rethink or repeat the data collection process. If you are satisfied with the data collected, you can then go ahead to make sense of the data so that you are able to present a solution or different solutions to the rest of the participants next week. | The analysis of the data involves responding to the questions above.

Remember, to ensure that data collected is reliable it may be necessary to repeat the experiment a number of times. Averages can then be calculated if further processing is needed - for example in the paper airplane enquiry. To ensure that the data is valid, make sure to consider the variables and which to control. }} | Remember, to ensure that data collected is reliable it may be necessary to repeat the experiment a number of times.
