Final answer:
In a marketing experiment, the dependent variable is usually the outcome measured by the researcher. Sales revenue is a likely dependent variable in such experiments because it is the most immediate indicator of the effectiveness of marketing strategies.
Step-by-step explanation:
The question being asked is related to identifying the dependent variable in a marketing experiment conducted by a market researcher. In most marketing experiments, the dependent variable is the outcome that the researcher wants to measure, which is influenced by the manipulation of the independent variable. Among the options provided (sales revenue, number of customers, advertising budget, and market share), the sales revenue is a likely dependent variable because it is what the marketing experiment will most immediately affect and is a clear indicator of business success after implementing marketing strategies.
To elaborate further, marketing researchers often look at sales revenue to determine the effectiveness of various marketing campaigns or changes in strategy. The number of customers and market share can also be dependent variables; however, these are more likely to be monitored in other types of research experiments. The advertising budget is typically an independent variable, as it is something the company will manipulate to see how it impacts sales revenue or other outcomes
