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 11
A biologist records the number of bacteria colonies on a petri dish every hour for 6 hours. What is the dependent variable in this experiment?
A researcher finds a correlation coefficient of 0.95 between two variables. What does this indicate about the relationship between the variables?
Describe one limitation of using only the mean to summarize a data set.
Describe one way to minimize bias in data collection during a biological experiment.

A researcher wants to know if there is a relationship between hours of sunlight and plant growth. Which type of graph should be used? (1) Bar graph (2) Pie chart (3) Scatter plot (4) Histogram
A student collects data on plant growth under different light conditions. Which type of graph is most appropriate to display the average height of plants for each light condition? (1) Line graph (2) Bar graph (3) Pie chart (4) Scatter plot
A student measures the heart rate of 10 students before and after exercise. What type of data analysis would be most appropriate to determine if exercise affects heart rate? (1) Paired t-test (2) Chi-square test (3) ANOVA (4) Regression analysis
A student observes that as the temperature increases, the rate of enzyme activity also increases up to a point, then decreases. What type of relationship is this? (1) Linear (2) Nonlinear (3) No relationship (4) Inverse
Fill in the blank: A __________ variable is one that is kept constant throughout an experiment.
Fill in the blank: In a data set, the __________ is calculated by subtracting the smallest value from the largest value.
Fill in the blank: The __________ is the middle value when data are arranged in order.
Fill in the blank: The __________ is the value that appears most frequently in a data set.
A researcher finds that the p-value for their experiment is 0.08. Is this result typically considered statistically significant? (Yes/No)
True or False: A scatter plot is useful for showing the relationship between two continuous variables.
True or False: Correlation implies causation in biological data analysis.
True or False: Data interpretation involves drawing conclusions based on the analysis of collected data.
