A data analyst analyzes the data for state traffic violations within Microsoft Excel. The analyst is only interested in fines for speeding violations. How should this analyst narrow the scope of the data?
Filter out nonspeeding violations.
To focus solely on speeding violations, the analyst should apply a filter to exclude all nonspeeding violations, thereby honing in on the relevant data for analysis.
Sorting the data by speeding violation fines would organize the fines in order, but it does not eliminate nonspeeding violations from the dataset. This approach does not narrow the scope; it merely rearranges the existing data, leaving irrelevant entries intact.
Sorting by nonspeeding fines would emphasize the fines related to violations that the analyst is not interested in. This would further distract from the objective, as it would still include irrelevant data while providing no focus on speeding violations.
Filtering out speeding violations would result in removing the very data the analyst needs to analyze. This action would contradict the goal of focusing on speeding fines and would leave the analyst with no relevant information to work with.
Filtering out nonspeeding violations effectively narrows the dataset to only include speeding violations. This method allows the analyst to concentrate exclusively on the fines associated with speeding, aligning perfectly with the task at hand.
To effectively analyze only the fines for speeding violations, the analyst must filter out nonspeeding violations. This selective filtering process ensures that the analyst works with a focused dataset that directly supports their research objectives, making the analysis more efficient and relevant.
