Explain how statistics are a tool.
What will be an ideal response?
Statistics provide the tools one needs to better understand the data. Statistics can help one summarize the scores (e.g., On average, how satisfied are your customers?), examine how different the scores are from participant to participant (e.g., What is the range of scores in the data set?), display the average scores in organized graphs and tables, and test predictions one may have about average scores in different groups of participants or from the same participants at different times. One can even use statistics to examine relationships between different sets of data (e.g., Are customers with more information about your company more satisfied with your company's products?).
