Read the first 7 Data Analytics & Visualization flashcards as text

  1. A retail tobacco manager wants to track whether a new loyalty program increased average spend per visit. Which statistical comparison is most relevant?

    Answer: Compare mean transaction value before and after program launch

    Comparing the mean transaction value before and after the program launch directly measures whether the loyalty program influenced spending.

  2. Which data visualization principle helps prevent misleading comparisons in tobacco retail reports?

    Answer: Starting the y-axis at zero to accurately represent magnitude differences

    Starting the y-axis at zero ensures that bar heights accurately reflect the true proportional differences between values.

  3. A cigar retailer notices that a particular brand's sales drop every summer. What type of data pattern is this?

    Answer: Seasonal variation

    Seasonal variation refers to predictable, recurring fluctuations in data that follow a calendar-based pattern such as summer declines.

  4. What is the benefit of using a rolling 4-week average instead of daily sales figures when reporting tobacco retail performance?

    Answer: It smooths out day-to-day volatility to reveal the underlying trend

    A rolling average smooths short-term fluctuations, making it easier to see the true direction of the sales trend.

  5. A tobacconist's POS system exports data in CSV format. What is the first step before analyzing this data in a spreadsheet tool?

    Answer: Clean the data by checking for duplicates, missing values, and formatting errors

    Data cleaning removes duplicates, corrects errors, and addresses missing values to ensure analysis produces accurate, reliable results.

  6. Which metric would a tobacconist use to measure the average revenue generated per customer visit?

    Answer: Average transaction value (ATV)

    Average transaction value (ATV) is calculated by dividing total revenue by the number of transactions, reflecting revenue per visit.

  7. When a retail tobacco dashboard shows a metric colored red, yellow, or green, what data visualization technique is being used?

    Answer: Traffic light (RAG) status coding

    Traffic light or RAG (Red-Amber-Green) status coding uses color to instantly communicate whether a metric is on target, at risk, or failing.
