Question

after reading the openstax reference pages, use the drop - down menus to categorize the following as accurate and/or precise.
is not accurate but is precise
is accurate but not precise
is accurate and precise
is neither accurate nor precise

Explanation:

• First target: The single dot is at the center. So it is accurate (close to the true value - the center) and since there is only one measurement (but if we consider in terms of precision which is about reproducibility of close - by values, here if we assume it's a single - shot perfect, we can say it's accurate and precise).
• Second target: The dots are close to each other (precise) but not at the center (not accurate).
• Third target: The dots are spread out (not precise) and not at the center (not accurate).
• Fourth target: The dots are close to each other (precise) and close to the center (accurate).

Answer:

1. Is accurate and precise
2. Is not accurate but is precise
3. Is neither accurate nor precise
4. Is accurate and precise
