Final answer:
The observational study conducted at Ordway Elementary School that found 23% of drivers were speeding is an example of Descriptive Statistics, which summarizes data without making inferences about a larger population.
Step-by-step explanation:
The observational study where it was noted that 23% of drivers passing in front of Ordway Elementary School between 7 a.m. and 8 a.m. were speeding is an example of B. Descriptive Statistics. Descriptive statistics involve summarizing and organizing the data so that it can be understood, and usually involves the calculation of percentages, means, and other summaries of data. In this case, the percentage (23%) of drivers speeding is a summary of the data collected during the observation period, describing a characteristic of the group under study without making any inferences or predictions about a larger population. The data has not been used to generalize or infer information about a larger group, which would be necessary for it to be considered inferential statistics.
