Which graph represents continuous data and connects data points with a line, typically plotting the independent variable on the X-axis and the dependent variable on the Y-axis?

Which graph represents continuous data and connects data points with a line, typically plotting the independent variable on the X-axis and the dependent variable on the Y-axis?

• A. Histograms
• B. Line Graphs
• C. Scatter plots
• D. Bar charts

Answer: (B)

Line graphs are used when you have continuous data and want to see how the dependent variable changes as the independent variable changes, usually over time. The data points are connected with a line, which emphasizes continuity from one value to the next on the x-axis to the y-axis. This makes trends, rises, or falls easy to spot and helps you track how the measurement evolves. Histograms show the distribution of a single continuous variable by grouping values into bins and are made of separate bars, not a connected line. Scatter plots display individual data points for two variables with no line joining them, so they illustrate relationships rather than a continuous change over an axis. Bar charts compare distinct categories with separate bars and also do not depict continuity.
