Data Collection Methods
Biology ⇒ Scientific Inquiry and Experimental Design in Biology
Data Collection Methods starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Data Collection Methods.
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 12
Describe how a double-blind procedure can improve data collection in biological experiments.
Describe one advantage and one disadvantage of using interviews as a data collection method in biology.
Describe one way to minimize human error during data collection in a biology experiment.
Describe the difference between qualitative and quantitative data in biological research.
A researcher collects data on the number of stomata per leaf in 50 plants. What type of sampling is this? (1) Random sampling, (2) Systematic sampling, (3) Stratified sampling, (4) Cluster sampling

Fill in the blank: Data that can be placed into categories, such as blood type or flower color, is called __________ data.
Fill in the blank: In a controlled experiment, the group that does not receive the experimental treatment is called the __________ group.
Fill in the blank: The accuracy and consistency of a measurement is referred to as its __________.
Fill in the blank: The group in an experiment that receives the treatment is called the __________ group.
True or False: Convenience sampling is the best method to ensure a representative sample in biological research.
True or False: Data collected from secondary sources is always more reliable than primary data.
True or False: Data should always be recorded immediately after observation to avoid loss or distortion of information.
True or False: Observer bias can affect the accuracy of data collected through observation.
