AP PSYCHOLOGY

Detailed explanation-1: -A dot plot is like a bar chart in that it indicates values for different categorical groupings, but encodes values based on a point’s position rather than a bar’s length. Dot plots are useful when you need to compare across categories, but the zero baseline is not informative or useful.

Detailed explanation-2: -Line Graph A line graph reveals trends or progress over time and you can use it to show many different categories of data.

Detailed explanation-3: -an Area Graph. Area graphs are very similar to line graphs. They can be used to track changes over time for one or more groups. Area graphs are good to use when you are tracking the changes in two or more related groups that make up one whole category (for example public and private groups).

Detailed explanation-4: -Histograms are useful for displaying continuous data. Bar graphs, line graphs, and histograms have an x-and y-axis.

Detailed explanation-5: -Categorical or nominal data: appropriate for bar charts Bar charts make sense for categorical or nominal data, since they are measured on a scale with specific possible values. With categorical data, the sample is often divided into groups, and the responses have a defined order.
