    Question

    In a machine learning experiment, the company wants to

    predict future sales based on advertising spend. What is the dependent variable in this scenario?
    A Advertising Spend Correct Answer Incorrect Answer
    B Sales Correct Answer Incorrect Answer
    C Market Trends Correct Answer Incorrect Answer
    D Competitor Data Correct Answer Incorrect Answer
    E Customer Sentiment Correct Answer Incorrect Answer

    Solution

    The correct answer is B , as the dependent variable is what the model aims to predict or explain. In this case, sales depend on factors such as advertising spend, making it the dependent variable in the experiment. Option A : Advertising spend is the independent variable, used to predict the dependent variable (sales). Option C : Market trends are external factors but are not explicitly defined as variables in this scenario. Option D : Competitor data might influence results but is not directly relevant here. Option E : Customer sentiment could correlate with sales but is not part of this specific analysis.
