find the (a) mean, (b) median, (c) mode, and (d) midrange for the given sample data. Express answers with the appropriate units of measurement. Then answer the given questions. Listed below are the amounts of mercury (in parts per million, or ppm) found in tuna sushi sampled at different stores in New York City. The study was sponsored by the New York Times and the stores (in order) are D'Agostino, Eli's Manhattan, Fairway, Food Emporium, Gourmet Garage, Grace's Marketplace, and Whole Foods. Which store has the healthiest tuna? Does it appear that the different stores get their tuna from the same supplier?

Key Concepts

Units of Measurement

Reporting units of measurement, such as parts per million (ppm) in this context, is crucial to maintain the precision and relevance of the analysis. It communicates the scale and the magnitude of the measurements accurately.

Midrange

The midrange is calculated by taking the average of the smallest and largest values in a data set. It offers a simple measure of the central location but may be influenced by extreme values.

Comparative Analysis in Data Interpretation

When comparing data from different groups or sources, such as the mercury levels in tuna from various stores, one can infer relative quality or healthiness. This involves identifying the store with the lowest mercury reading as having the healthiest tuna, and considering variations across stores may indicate differences in supply sources.

Median

The median is the middle value in a sorted list of numbers. It is used as a measure of central tendency that is less affected by outliers or skewed data, providing a robust indicator of where the center lies.

Mean

The mean is a measure of central tendency calculated by summing all the data values and dividing by the count of values. It provides an average value that summarises the overall level of the data set.

Mode

The mode is the value that appears most frequently in a data set. It highlights the most common or popular value and can be useful in understanding the repeated or dominant occurrence within the data.
