Graphs
Graphs often collect a set of data in a group of people. There are many kinds of graphs: pie charts (circle charts), bar graphs, line graphs, data tables, pictographs, flow charts, histograms, etc.

Which part of the graph can be used to explain what data bars or pie chart sections?
It is the legend or key.
What is the calculation to find the slope on a line graph?
Given the points A = (xa, ya) and B = (xb, yb), then the slope is
(ya - yb)/(xa - xb) or, equivalently, (yb - ya)/(xb - xa).
The equation is sometimes referred to as "rise"/"run".
How is the graph of mc020-1jpg different from the graph of mc020-2jpg?
Without access to the specific graphs mc020-1jpg and mc020-2jpg, I can't provide a direct comparison. However, generally, differences between two graphs could include variations in their shapes, slopes, intercepts, or overall trends, such as one graph exhibiting exponential growth while the other shows linear growth. Additionally, the scale of the axes or the range of values represented could also differ, affecting their appearance and interpretation. For a precise analysis, you would need to describe the key features of each graph.
What does a straight line mean on a speed time graph?
It means a constant acceleration:
* If the line slopes up, the object is getting faster at a constant rate;
* if it slopes down, the object is getting slower at a constant rate;
* If the line is horizontal, the object is neither speeding up nor slowing down, but travelling with a constant speed.
How do you find size of sector angle on the pie chart of a budget?
Calculate the percentage of a sector relative to the budge total. The angle for that sector is 3.6 times the percentage.
What is bar graph for greenhouse effect?
The answer will depend on what aspect of the greenhouse effect you wish to show. The pie could represent the mass of greenhouse gases in the atmosphere, or their volumes, or the amount of temperature change that can be attributed to each of the gases.
How To Calculate The Size Of An Angle In A Pie Chart?
Calculate the percentage that a particular sector represents of the total value. Then the angle size is 3.6 times the percentage.
Which Type Of Chart Would Be Best show the percentage of your total spendings on one category?
A pie chart.
How do you work out the range from a bar graph?
It is the height of the tallest bar minus the height of the shortest.
What are variables when your using a graph?
You can have almost any variables that you like. One of my favourites is Minard's graph depicting Napoleon's army marching to Russia and retreating. See en.wikipedia.org/wiki/French_invasion_of_Russia#Weather_as_a_factor. The graph depicts the size of the army, distance from Paris/Moscow (including some geographical features) and the temperatures (lower section) : all plotted against time.
What are the purposes of a graph?
There are two main purposes. One purpose is for pattern recognition. Humans are very good at recognising patterns such as [linear] trends, cyclical patterns, clusters and so on. This is useful for preliminary investigation of data.
The second purpose is to illustrate summary data in a quick-and-easy way.
Which information would be best shown on a bar graph?
A bar graph is best suited for displaying categorical data, where individual categories can be compared against each other. For example, it effectively illustrates the sales figures of different products, the number of votes received by candidates, or the population sizes of various cities. Bar graphs clearly depict differences in magnitude and allow for easy visual comparisons across categories. Additionally, they can represent both discrete and continuous data when grouped into categories.
Bar Charts are used to compare things between different groups or tracking the changes according to time.
Which part of graph can be used to explain what data bars or pie chart sections represents?

How are bar graphs and picture graph are alike?
Bar graphs and picture graphs are alike in that both visually represent data to facilitate comparison and analysis. They use distinct categories along one axis and display quantities or frequencies, making it easy to interpret information at a glance. Additionally, both types of graphs can effectively convey trends and patterns in the data being presented.
