Question

A statistician prepared a bar chart showing, in descending order, the frequency of six underlying causes of general aviation accidents (pilot error, mechanical problems, disorientation, miscommunication, controller error, other). what would we call this type of chart? pivot table pareto chart log scale chart frequency polygon

Answer 1

The answer is: Pareto chart

Pareto chart is the combination of line and bar graphs. This type of chart is usually used to present data with frequency of nonoccurence and unite measurement at the same time.(frequency of accidents and number of factors that cause the accidents. )

Other than that, Pareto chart is also commonly used in quality control or searching the highest cause of defects.

Answer 2

The option (B) is correct. The chart prepared by the statistician showing the frequency of six underlying causes of general aviation accidents, in descending order is Pareto chart

Further Explanation:

Pareto chart: It is a chart type that consists of both a line graph and bars, where the line graph is used to represent the cumulative total and bars are used to represent individual values in descending order.

Justification for the correct and incorrect answer:

A.

Pivot table: This option is incorrect.

It is a table that is used in statistics to summarizes the data from a more extensive table like a database, business intelligence program, or spreadsheet. The graphs can be prepared by using the pivot table.

B.

Pareto chart: This option is correct.  

It is a chart type that consists of both a line graph and bars, where the line graph is used to represent the cumulative total and bars are used to represent individual values in descending order.

C.

Log scale chart: This option is incorrect.

It is a type of chart that uses a scale in which two equivalent changes in the price are represented using the same vertical distance on the scale.

D.

Frequency polygon: This option is incorrect.

It is a graph prepared by joining midpoints of every bin or interval with the help of the line.

Therefore, the chart prepared by the statistician is a Pareto chart.
