Data interpretation is a vital component of statistics, as it involves organizing data into tables, charts, or graphs to derive logical and statistical conclusions. This process is essential for accurately presenting research findings.
An effective way to describe a dataset is through central tendency values, which provide a single representative value for the entire set. For instance, the mode is the most frequently occurring value in a dataset.
To illustrate, let's consider the following series of numbers: 15, 21, 19, 19, 17, 16, 17, 18, 19, 18. In order to find the median, we must first arrange the data in ascending order: 15, 16, 17, 17, 18, 18, 19, 19, 19, 21. As there is an odd number of values, the median will be the middle number, which is 17. The third quartile, or the value to the right of the median, will be 19. The minimum value in this dataset is 15 and the maximum is 21. This information can be visually represented using a box plot, as shown below.
