Data Analysis and Interpretation
Biology ⇒ Scientific Inquiry and Experimental Design in Biology
Data Analysis and Interpretation starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Data Analysis and Interpretation.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 7
A student finds that the mode of a data set is 7. What does this mean?
A student observes that the number of insects increases as the temperature rises. What conclusion can be drawn from this observation?
Describe one way to check if your data is reliable.
Explain the difference between qualitative and quantitative data.
A scientist observes that as the temperature increases, the rate of plant growth also increases. What kind of relationship is this? (1) Negative correlation (2) No correlation (3) Positive correlation (4) Inverse relationship
A student collects data on the number of birds seen each day for a week: 3, 5, 2, 4, 6, 5, 3. What is the mean number of birds seen per day?
A student finds that the average height of 5 plants is 12 cm. If the heights are 10, 12, 11, 13, and 14 cm, is the calculation correct?
