State True or False :

(i) Graphs let the audience visualize trends quickly.

(ii) Graphs are a compact way to show information.

(iii) Graphs make it hard to find the main point of some data.

(iv) Graphs add a visual model to a presentation.

(v) Graphs are not good at showing changes and relationships.

(vi) Line graphs are good at showing changes over time.

(vii) Line Graphs are also called histograms.

(viii) Pie Charts show how parts relate to the whole.

(ix) Pie Charts can make multiple comparisons.

(x) Bar Graphs and Line Graphs show trends.

(i) True
Reason — Graphs are visual representations that allow viewers to quickly identify trends and patterns in data.

(ii) True
Reason — Graphs are visual representations, thus making it easier to grasp and understand information.

(iii) False
Reason — Graphs are designed to enhance data visualization and understanding. They generally make it easier, not harder, to identify the main point or trends in the data.

(iv) True
Reason — Graphs indeed introduce a visual model to a presentation, helping to illustrate data patterns and trends more effectively than raw numbers.

(v) False
Reason — Graphs are specifically designed to show changes and relationships in data, making them a powerful tool for data visualization.

(vi) True
Reason — Line graphs are particularly effective at displaying changes over time, as they connect data points with lines, highlighting trends and fluctuations.

(vii) False
Reason — Line graphs and histograms are different. Line graphs display the relationship between two variables over a continuous range, while histograms show the distribution of data within intervals or bins.

(viii) True
Reason — Pie charts are suitable for illustrating how different parts contribute to a whole, providing a clear visual representation of proportions.

(ix) False
Reason — Pie charts are best used to show the proportion of parts in relation to a whole.

(x) True
Reason — Both bar graphs and line graphs are excellent for presenting trends in data. Bar graphs use bars of varying lengths to compare different categories, while line graphs depict changes over time or other continuous variables using lines connecting data points.
