You can also refer to this type as a quantitative data set, as the numerical values can apply to mathematical calculations when necessary. Many financial analysis processes also rely on numerical data sets, as the values in the set can represent numbers in dollar amounts. WebbOn the downside, a box plot’s simplicity also sets limitations on the density of data that it can show. With a box plot, we miss out on the ability to observe the detailed shape of distribution, such as if there are oddities in a distribution’s modality (number of ‘humps’ or peaks) and skew. WebbYour data may be normally distributed (i.e. with a symmetrical, bell-shaped curve) and so parametric, or they may be skewed and therefore non-parametric. You can explore and describe the shape of data using graphs: Tally plots – a simple frequency plot. Histograms – a frequency plot like a bar chart. You can also use shape statistics: rays mariners
