Drunk-Driving Fatalities. Drunk-driving fatalities represent the total number of people (occupants and non-occupants) killed in motor vehicle traffic crashes in which at least one driver had a blood alcohol content (BAC) of or higher. The following graph is based on data published by the National Highway Traffic Safety Administration in Federal Highway Administration Annual Highway Statistics.
a. What features of the graph are potentially misleading?
b. Do you think that it was necessary to incorporate those features in order to display the data?
c. What could be done to more correctly display the data?
Step-by-Step Solution
Verified(a) The vertical axis does not begin at
(b) It's a pointless feature
(c) Redraw the graph with reduced vertical axes that starts from .
The given data is
The graph may be deceiving since the strongly increasing trend in the licenced driver is emphasised because the vertical axis does not begin at zero.
The given data is
Line graphs are one of the most common and effective visual techniques for displaying data trends or a specific correlation across time. To demonstrate trends over time, the values are plotted on the chart and points are joined. Simple, numerous, and compound line graphs are the three forms of line graphs. They're utilized to assess many types of data.
According to the information, It's a pointless feature because the same information can be extracted from the graph if the axes are set to zero.
The given data is
Tables, charts, and graphs are all different types of data representations that can be utilised for two different reasons. The first is to assist with data gathering, organisation, and analysis as part of a scientific investigation.
We need to redraw the graph with reduced vertical axes that starts from
