Using Graphs in Science

Three commonly used types of graphs are **bar graphs, circle graphs, and line graphs**.

Graphing is an important procedure used by scientists **to display the data that is collected during a controlled experiment**. The most common type of graph used in biology is a line graph.

These are **line graphs and histograms**. I. Making a Line Graph - Data from Experiments: this kind of data is often displayed in a line graph. A line graph would be used to show the effect of fertilizer concentration on plant growth.

Using Graphs in Science

Three commonly used types of graphs are **bar graphs, circle graphs, and line graphs**.

Most graphs included in Biology reports and scientific papers, are **scatter plots, line plots, box plots, and bar graphs** as shown below, An easy way to draw these graphs is to use the free software jamovi available here.

The formal term to describe a straight line graph is **linear**, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear. y.

**Some things to consider when constructing a graph:**

- Identify the variables that you are going to plot, and decide which axis you want to plot each variable.
- Determine the variable range and the scale of the graph.
- Label and number each axis.
- Plot the data points.
- Draw the graph.

In science the term is used in both ways. For example, Anderson (1997) stated more generally: "diagrams are pictorial, yet abstract, representations of information, and **maps, line graphs, bar charts, engineering blueprints, and architects' sketches** are all examples of diagrams, whereas photographs and video are not".

**Introduction**

- Take a quick poll from students on what their favorite season is.
- Use tally marks, and record results on the board.
- Tell students that today they are going to use data to make bar graphs. Explain to the students that data are facts or statistics that are collected to help us learn more about something.

the **4** most common are probably line graph, bar graphs and histogram ,pie charts, and Cartesian graphs.

Graphs are **visual representations of data collected**. They often helped us in showing the trend of the data. They are used in various fields and it is of immense help to the people. The purpose of drawing a graph is to show numerical facts in usual form so that they can be understood quickly, easily and clearly.

**Help them master bar graphs, line graphs, scatter plots, pie charts, and more with these fun and creative graphing activities!**

- Make an anchor chart or two.
- Introduce graphing with a pocket chart.
- Snack and graph with treats.
- Use toys to make a pictograph.
- Graph the water bottle challenge.
- Measure and graph your thumbs.

Reasoning questions can be classified under four headings:**Data interpretation (line graphs, data/numerical tables, bar graphs, pie charts and combination charts)** **Data sufficiency**. **Analytical reasoning**. **Logical reasoning**.

**Contents**

- 1 Distance-time Graphs.
- 2 Position-time Graphs or Displacement - Time Graphs.
- 3 Velocity-time Graphs.

A double bar graph is **the graphical representation of grouped data**. In a double bar graph, two bars are drawn for each category. These two bars represent the two given parameters for each category. The x-axis is used to represent the different items/categories. The y-axis is used to represent the two parameters.
