Understanding Scale, Outlier, Range, and Plotting Graphs

What is the definition of scale in graphing?

• The act of arranging objects in a particular order

• Ratio of a drawing or model to the actual size of the object being represented

• The largest data point and the smallest data point to help create a graph.

• The technique of solving mathematical equations

Define an outlier in a data set.

• A data point that significantly differs from other data points in the set.

• A data point that is within the normal range of other data points in the set.

• A data point that is the average of all the other data points in the set.

• A data point that is not relevant to the analysis of the data set.

What is the range of a data set?

• The range of a data set is the average of all the values in the set.

• The range of a data set is the sum of all the values in the set.

• The range of a data set is the difference between the maximum and minimum values in the set.

• The range of a data set is the median value in the set.

Explain how to calculate the range of a data set.

• Range = Maximum value - Minimum value

• Range = Maximum value / Minimum value.

• Range = Maximum value * Minimum value.

• Range = Maximum value + Minimum value.

What are the different types of graphs used to represent data?

• bar charts, line charts, area charts, bubble charts

• bar graphs, line graphs, pie charts, scatter plots, and histograms

• box plots, radar charts, stacked bar charts, treemaps

• network graphs, heat maps, donut charts, waterfall charts

When would you use a bar graph to represent data?

• When comparing different categories or groups.

• When representing data with continuous variables.

• When displaying numerical data.

• When analyzing trends over time.

What is the purpose of a line graph?

• To display categorical data

• To compare data across different categories

• To show the relationship between two variables over a continuous interval.

• To show the distribution of a single variable
