What does the yellow line represent? Today’s World: The amount of global warming that is likely to occur if CO2 emissions cease immediately and CO2 concentrations continue at their current level. You just studied 15 terms!

Thinning plus prescribed burning significantly reduces the tree survival rate compared to the control and thinned treatments. It reduces the amount of fuel on the ground so that a wildfire never reaches the critical heat required to kill most of the trees.

Both involve aposematic coloration, or warning signals, to avoid being attacked by a predator. In Batesian mimicry, a palatable, harmless prey species mimics the appearance of another species that is noxious to predators, thus reducing the mimic’s risk of attack. This form of mimicry is seen in many insects.

A bar graph is a two-dimensional display of data in a bar format. This format allows you to compare characteristics and frequencies such as quantity and price between and within groups of data. Required bar graph titles include the name of the graph, the title of the vertical axes, and the title of the horizontal axes.

Titling the Graph The proper form for a graph title is “y-axis variable vs. x-axis variable.” For example, if you were comparing the the amount of fertilizer to how much a plant grew, the amount of fertilizer would be the independent, or x-axis variable and the growth would be the dependent, or y-axis variable.

Bar graphs are used to compare things between different groups or to track changes over time.

A double bar graph is a graphical display of information using bars at various height to compare two data groups. Therefore, a double bar graph is useful while comparing enrolment of students in class VII in 2009 and 2010 and for marks obtained in term I and term II examinations.

Histograms are used to show distributions of variables while bar charts are used to compare variables. Histograms plot quantitative data with ranges of the data grouped into bins or intervals while bar charts plot categorical data.

Pie charts and bar charts can both be effective methods of portraying qualitative data. Bar charts are better when there are more than just a few categories and for comparing two or more distributions.

Pareto charts are used to represent qualitative data. A Pareto chart is a vertical bar graph in which the height of each bar represents either the frequency or the relative frequency. A scatter plot is used when we have paired data with both coordinates being quantitative values.
