Final Answer:
False. In a scatter plot, points are not necessarily connected with a line. A scatter plot is used to visualize the relationship between two variables by plotting individual data points, and connecting them with a line may not accurately represent the underlying data distribution.
Step-by-step explanation:
A scatter plot is a graphical representation of data points in a two-dimensional space, with each point representing the values of two variables. The primary purpose of a scatter plot is to observe patterns, trends, or relationships between variables, and it is particularly useful for identifying correlations. Connecting points with a line in a scatter plot is not a standard practice because it can potentially introduce a misleading representation of the data. The absence of a connecting line allows for a more accurate interpretation of the individual data points and their distribution.
Connecting points with a line in a scatter plot is akin to implying a continuous relationship between the variables, which may not be valid. The strength of a scatter plot lies in its ability to show the dispersion of data points and highlight any discernible patterns or clusters. A line connecting points might suggest a continuous trend that doesn't exist, leading to misinterpretations. Therefore, the decision to connect points with a line should be made carefully, considering the nature of the data and the insights sought from the visualization.
