     The extra digits after the decimal point don’t add any real meaning. They simply make the
                        number look more detailed.

                     This is why it’s important to understand the original data and its precision. Metadata, which is
                     information about data, often stores details about its precision and accuracy.

                     THINKING LIKE A DATA ANALYST

                     Imagine you’re tracking your daily study time and you want to see if studying for longer helps you

                     improve your grades. This is where you can think like a data analyst.

                      Step 1: Observing carefully: You start by observing how much time you spend studying each
                        day  and the grades you  get  for  your

                        assignments.                                      Date         Hours Studied         Grade
                      Step 2: Organising information: Next,        Monday            1 hour                 70%
                        you  organise the data by creating           Tuesday           2 hours                80%
                        a table. You write  down how many            Wednesday         1.5 hours              75%

                        hours you studied and the grades you         Thursday          2.5 hours              85%
                        got each day or week.

                      Step 3: Looking for patterns: You start looking for patterns. For example, when you study for
                        more hours, your grade seems to be higher. You notice that on days when you studied for at
                        least 2 hours, your grades were better.
                      Step 4: Asking questions: You then ask, “Why do my grades improve when I study more?” Is it
                        because you have more time to review the material? Or maybe because you’re less distracted?

                      Step 5: Drawing conclusions: Based on your observations, you can draw a conclusion: “The
                        more I study, the better my grades seem to be.” This is a decision you can make and now you
                        know that studying more helps you improve!

                                                                                     Data Visualisation and Analysis   61
