Continuous data is a type of quantitative data that can take on any value within a certain range. Examples of continuous data include height, weight, temperature, and length. Continuous data is often obtained by measuring, and it can take on an uncountable set of values. In contrast, discrete data is a type of quantitative data that can only take certain fixed values. Examples of discrete data include the number of children attending a nursery each day, the number of each type of treatment a salon needs to schedule for the week, and the profit a business makes each month. Discrete data is often represented using tally charts, bar charts, or pie charts.

The key difference between continuous and discrete data is that continuous data can take on any value within a certain range, while discrete data can only take on certain fixed values. Continuous data is commonly displayed in visualizations such as histograms, while discrete data is often displayed using bar charts or pie charts.
