Final answer:
The objective of the research is to estimate a person's height from their shoe size, identifying B. Estimate height from shoe size as the correct answer. This involves analyzing the relationship between shoe size and height through statistical modeling and choosing the correct unit of measurement for data accuracy.
Step-by-step explanation:
The research's objective is to estimate a person's height (in centimeters) using their shoe size (in inches). Therefore, the correct answer is B. Estimate height from shoe size. This involves examining the relationship between shoe size and height, using statistical methods such as scatter plots, correlations, and regressions to create a model that can predict height based on shoe size. In this research, the shoe size serves as the independent variable, and the height is the dependent variable that the researchers aim to estimate.
When dealing with measurements and data collection, it is important to choose the correct unit of measurement. Inches are the optimal choice for measuring shoe size since most feet are less than 12 inches. Recording the number of pairs of shoes owned by classmates or surveying the average shoe size could help the researchers in further understanding trends and variations within their data. Additionally, calculations such as the correlation coefficient or least-squares line help in determining the strength and nature of the relationship between shoe size and height.
