Seed dispersal: data analysis
Lesson details
Learning outcome
I can display data as a graph or chart and identify patterns to conclude on the relationship between the independent and dependent variable.
Key learning points
- Experimental data can be analysed by plotting data on a line graph or bar chart.
- Line graphs are used where the independent variable is continuous; bar charts are used where it is categoric.
- Drawing a bar chart and/or line graph follows a set format.
- A line of best fit on a line graph indicates the trend (relationship between in the independent and dependent variable).
Keywords
Line graph - A line graph displays data where the independent and dependent variables are continuous.
Bar chart - A bar chart displays data where the independent variable is categoric.
Line of best fit - A smooth line on a line graph that indicates the trend in the data is called the line of best fit.
Trend - A trend is a pattern in the data that shows the relationship between the independent and dependent variable.
Common misconception
Labelling the x-axis with the values investigated instead of an evenly spaced range; or putting the axes the wrong way round for independent and dependent variables.
Clearly showing the placement of variables in the table and on the graphs, step-by-step guidance of drawing the graphs.
Teacher tip
Work through the graph drawing slowly, getting pupils to do one step at a time.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
