Get Graphing Lab Biology Answer Key

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.

How to make a graph Identify your independent and dependent variables. Choose the correct type of graph by determining whether each variable is continuous or not. Determine the values that are going to go on the X and Y axis. ... Label the X and Y axis, including units. Graph your data.

So to review, graphs are an organized way to show data. X-Y graphs show how an independent variable on the X-axis relates to a dependent variable on the Y-axis. Line graphs also have X and Y axes but track changes that take place usually over time. Area graphs are a combination of multiple line graphs.

Drawing line graphs plot the data by using a scale such as one large square = 3 or 6. Write the name of each axis and the correct unit, e.g. rate of water loss/g per h, temperature/°C, time/s. Plot the points exactly using a sharp pencil. Draw the points lightly so that you can rub them out if you need to.

The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space.

Graphs are also used for knowledge representation in the Gene Ontology (GO) [4], and bipartite graphs between biological concepts and scientific papers that are written about them [5] are another form of knowledge representation. A second application of graphs to molecular biology is to model measured data.

A graph has the following main parts: the cartesian plane for space, the x and y-axes, the points and lines, and the labels of the axes.

Bar charts are used to show data on discontinuous variables, for example blood groups, eye colour, etc.; histograms are used to show data on continuous variables, e.g. length, mass, speed, volume, etc.
