Question 34

The store owner is looking for the mean sales for each day of the week.

To determine the average sales for each day of the week, the store owner seeks the mean, which is calculated by summing all sales figures and dividing by the number of days.

A) Median

The median represents the middle value when sales figures are sorted in order, which does not serve the purpose of finding an average. While it can provide insight into sales trends, it does not represent the overall average sales for the days in question.

B) Mean

The mean is the appropriate statistic for calculating the average sales, as it takes all sales data into account and provides a single value that represents the total sales divided by the number of days. This is exactly what the store owner needs to assess average daily sales.

C) Distribution

Distribution pertains to how sales figures are spread over a range and does not yield a single average value. While understanding distribution can be useful for sales analysis, it does not provide the specific average the store owner is seeking.

D) Variance

Variance measures the degree of variation in sales from the mean, indicating how much the sales figures differ from the average. However, it is not a measure of average sales itself and does not fulfill the store owner's requirement for an average.

Conclusion

The mean is definitively the correct answer as it provides the average sales needed by the store owner. The median, distribution, and variance do not fulfill this requirement as they either focus on different aspects of the data or do not provide a direct measure of average sales.
