Final answer:
Quantitative research techniques for measuring brand equity include A) surveys and D) experiments, as they provide numerical data suitable for statistical analysis.
Step-by-step explanation:
Quantitative research techniques are used to gather numerical data that can be used to make inferences about larger populations. Among the listed techniques, surveys and experiments are the two that are typically associated with quantitative research methods for measuring brand equity.
Surveys collect quantifiable data from participants as they respond to structured questions, allowing researchers to analyze responses using statistical tools to draw conclusions about brand equity. On the other hand, experiments can be designed to test hypotheses about brand equity by manipulating certain variables and measuring their effect, providing a controlled method to obtain quantitative data.
Other methods like focus groups and observations are generally qualitative and provide in-depth insights but do not typically generate the numerical data needed to quantify brand equity.
