Final answer:
Option C: An observation in a spreadsheet is all the data in a specific row, which in this case pertains to the 'High Point' referred to in row 10. It is a collection of data points relevant to a particular instance within the dataset.
Step-by-step explanation:
In the context of a spreadsheet, the term that describes all of the data in row 10 for the variable 'High Point' is the observation. This consists of all the data points or values associated with a single instance in a dataset. For example, in a class dataset, if each row represents a different student, then the data in row 10 would include all the observations for that particular student, such as quiz scores, assignment marks, and other relevant information.
Collecting data is an essential practice in various fields including science, business, and technology. Numbers can be collected and later categorized, such as reporting quiz scores as letter grades. When you 'describe the data', you analyze and summarize its characteristics to understand and convey its meaning accurately.
