๐ What is a Scatter Plot?
A scatter plot is a type of graph that uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.
๐ What are Other Graph Types?
There are many other types of graphs, each suited for different purposes. Some common examples include:
- ๐ Line graphs: Show trends over time.
- bar graphs: Compare different categories.
- ๐ฅง Pie charts: Show proportions of a whole.
- ๐บ๏ธ Histograms: Show the distribution of a single variable.
