A line graph displays data where the independent and dependent variables are continuous.

A bar chart displays data where the independent variable is categoric.

A smooth line on a line graph that indicates the trend in the data is called the line of best fit.

A trend is a pattern in the data that shows the relationship between the independent and dependent variable.

Seed dispersal: data analysis

Science

Pupils will learn about what the genome is, what it’s made of and where it’s stored, more detail about the chemical structure of DNA, and the relationship between an organism’s genome and its phenotype.

Pupils learned about changes experienced in puberty, the male and female reproductive systems, the menstrual cycle, sexual intercourse, gametes and fertilisation, gestation and birth, and the dangers of smoking, drinking and drugs during pregnancy.

Reproduction in plants

used where the independent variable is continuous

used where the independent variable is categoric

Match the type of graph or chart to its use.

draw an evenly spaced scale on the x-axis for the independent variable

draw an evenly spaced scale on the y-axis for the dependent variable

label both axes with descriptive titles and units

as the height dropped from decreases, the distance dispersed increases

as the height dropped from increases, the distance dispersed decreases

as the height dropped from increases, the distance dispersed increases

as the height dropped from decreases, the distance dispersed decreases

Match the variable to the axis it is plotted on.

What is the dependent variable on this bar chart?

the material of the model affected the distance dispersed

tissue dispersed triple the dispersal of card

paper dispersed almost double the distance of card but less than tissue

tissue dispersed double the distance of card

the height the model was dropped from affected the distance dispersed

Which conclusions can be drawn form this bar chart?

In the following investigation what is the dependent variable? 
How wing shape affects the distance seeds disperse.

In an investigation what do you use to collect your result in?

the number of seeds that do not germinate

distance from the light source to the seeds

In this investigation what is the independent variable? 
How distance from a light source effects the number of seed germinating.

When you collect repeat readings you can calculate a {{}}
