Graphing and Representation of Data
Biology ⇒ Scientific Inquiry and Experimental Design in Biology
Graphing and Representation of Data 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 Graphing and Representation of Data.
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
Describe how you would represent data from an experiment with more than one independent variable on a graph.
Describe one reason why it is important to use the correct type of graph for your data.
Explain the difference between a bar graph and a histogram.
Explain what a trend line in a scatter plot shows.
