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 9
A data set contains the following values: 2, 4, 4, 6, 8. What is the median?
A student collects data on the number of insects found under rocks in different locations. What is the dependent variable?
A student finds that the average height of plants in group A is 12 cm, and in group B is 15 cm. What is the difference in average height between the two groups?
A student measures the growth of bacteria in a petri dish every hour for 6 hours. What is the independent variable in this experiment?

A student observes that as the temperature increases, the rate of enzyme activity also increases. What type of relationship is this? (1) Negative correlation (2) No correlation (3) Positive correlation (4) Inverse relationship
A student records the heights of plants grown in different amounts of sunlight. What type of graph would best display this data? (1) Bar graph (2) Line graph (3) Pie chart (4) Scatter plot
If a student finds that their results do not support their hypothesis, what should they do next? (1) Change the data (2) Ignore the results (3) Analyze the data for errors and consider revising the hypothesis (4) Stop the experiment
Which of the following best describes a dependent variable? (1) It is kept constant (2) It is measured or observed (3) It is manipulated by the experimenter (4) It is unrelated to the experiment
Fill in the blank: A ________ is a summary of data that shows the frequency of each value or range of values.
Fill in the blank: A ________ is a visual representation of data that uses bars to compare different categories.
Fill in the blank: The ________ is the difference between the highest and lowest values in a data set.
Fill in the blank: The ________ is the middle value in a data set when the values are arranged in order.
True or False: A conclusion should be based only on the data collected, not on personal opinions.
True or False: A control group is necessary to interpret the results of an experiment accurately.
True or False: A scatter plot is useful for showing the relationship between two variables.
True or False: Data analysis can help scientists make predictions about future experiments.
