Question

a company is interested in producing a math game for smartphones and tablets. it selects a representative sample of boys and girls ages 4 to 8 who currently have access to a mobile device and are learning math. after interviewing the children and collecting other relevant data, the firm then makes generalizations about what all young children want in their math apps. the method used is
multiple choice
new product concept assessment.
secondary data collection.
sensitivity analysis.
statistical inference.
extrapolation.

Explanation:

Statistical inference involves using data from a sample (here, the representative sample of boys and girls ages 4 - 8) to make generalizations or draw conclusions about a larger population (all young children). New product concept assessment would focus more on evaluating the idea of the product itself in a more conceptual - design sense. Secondary data collection uses already - existing data, but here new data (through interviews) is being collected. Sensitivity analysis is about seeing how changes in variables affect outcomes. Extrapolation is usually about extending a trend, not about making generalizations from a sample to a population.

Answer:

statistical inference.
