Descriptive statistics summarize data for a variable by using measures like mean, median, mode, and standard deviation. It helps to understand the central tendency and variability of the data. On the other hand, inferential statistics helps to test hypotheses and draw conclusions from data by analyzing a sample and making inferences about the population. It also includes hypothesis testing and confidence intervals. Therefore, the correct option is B, i.e., descriptive statistics summarize data for a variable while inferential statistics test hypotheses and draw conclusion from data.
