Have you ever felt like you were drowning in data and were tempted to summarise it as an average? The central tendency is not your friend. Reducing data leads to a loss of information and while this can help make data sets manageable, there are techniques available to avoid this.

During the fourth session of the 2021 Measuring What Matters Symposium, speakers will discuss how intensive longitudinal data analysis can maximise the use of your collected data and allows you to answer a range of additional questions. If you’ve got a lot of data, why not try and use it all?
