Data Collection for Accuracy and Precision Flashcards
(20 cards)
What is accuracy in science?
Accuracy is how close your results are to the real or accepted value.
What is precision in science?
Precision is how close your results are to each other when repeated.
Can you be precise but not accurate?
Yes, your results can be consistent but far from the true value.
Can you be accurate but not precise?
Yes, your results can be close to the true value but vary a lot.
What does it mean to be both accurate and precise?
Your results are close to the true value and consistent.
What happens if you are neither accurate nor precise?
Your results are inconsistent and far from the true value.
Why is accuracy important in experiments?
Because it ensures the results reflect the true value.
Why is precision important in experiments?
Because it shows consistency and reliability in results.
What can affect the accuracy of an experiment?
Faulty equipment or human error, like forgetting to start a timer.
What can affect the precision of an experiment?
Using different tools or recording results inconsistently.
What is qualitative data?
Descriptive data about how something looks, smells, feels, or sounds.
What is quantitative data?
Data that is measured with numbers, such as weight or time.
Give an example of qualitative data.
The cookie was golden brown and crunchy.
Give an example of quantitative data.
The cookie weighed 20 grams and baked for 12 minutes.
Why are both qualitative and quantitative data important?
They help provide a complete picture of the experiment.
How should data be recorded during an experiment?
Write it down as you go, including date, time, and units.
Why should you be consistent when collecting data?
To ensure results are reliable and comparable.
Should you record mistakes or odd results?
Yes, they might reveal important patterns later.
How can you organize your data?
Use tables, charts, or apps like Google Sheets.
What does every good experiment begin and end with?
It begins with curiosity and ends with organized observation and data.
