Why we use graphs?
To represent the data Graphs give a visual representation of progress (or regress) and they are much quicker and easier to grasp than a boring stack of numbers.
What is the importance of bar graph?
Like all graphs , bar graphs give a visual representation of numerical data. This representation is designed to make it easier to understand the data it presents.It may also highlight the specific relevant features of the data. Bar graphs make it easyto compare the relative size of quantities, particular if the reader is more adept at judging the relative heights of bars than he is at mental arithmetic. scaling a bar graph can be used for two reasons, to jump past a large group of numbers unused (say the bar graph goes from 1-1000 but none of the data starts below 500)Scaling can be important to emphasize a difference in numbers too, suppose item a is at 700, item b is at 850, and item c is at 1000. if your bar graph jumps from 1 to 500 and then goes up in increments of 100, it can make 700 look like its far less than 850 or 1000. this is usually a business tactic done to impress board members when presenting lackluster numbers.
Can someone provide an explanation on why that is and maybe give an website on where you found it and How come in histograms the bars connect but not in the bar graphs?
Bar graphs are used for qualitative or discrete [quantitative] data. Values between the bar categories are not possible an to emphasise that, the bars have gaps between them. Conversely, histograms are used for continuous data and so the values on the "category" axis form a continuum. To illustrate this, the bars touch on another. I learned this well before the internet was widely available so did not need a website.
Which format for presenting statistics is best for enhancing comprehension and providing adequate information?
Graphs can give a quick summary.
What is a disadvantage to using graphs and diagrams?
1. The information may be in a form that is too difficult to use. 2. They sometimes give you too much information.
How do graphs help you to interpret data?
They give a visual interpretation of the data.
What tables or graphs give data over the longest period of time?
economic trends
Who uses graphs in spreadsheets and why?
Anyone who uses a spreadsheet can make use of graphs. They give a visual representation of data, often making it easier to understand. There are different kinds of graphs for different purposes, so different people can find graphs that are suitable for their needs. So they could be people involved in finance or they could be statisticians or mathematicians or business people, or students or people doing work at home for personal use.

Why do scientist use graphs when analyzing data?
Scientists use graphs while analyzing data to give a graphical or image based representation of the data that is more easily understandable as compared to the complex tabular or numerical data. Graphs make patterns and repetitions more obvious, and also clearly demonstrate deviations from the mean.
How are bar graphs and line graphs similar?
They both give you info.
Why do people make graphs?
Graphs give a quick and easy visual representation of a set of data. They help to demonstrate any correlation between data, and what direction the data seems to be moving in. They also make any anomalies clear because they would be visibly distant from the other data points. Both these things are useful because they wouldn't be as easy (or even possible) when just looking at a table of raw data.
Is it possible to grph data in Microsoft Excel 2003?
All versions of Excel give you lots of ways of creating graphs, which Excel refers to as charts.
Explain how graphs are used and what their advantages are?
Graphs give a very rapid visual of trends that may exist in data. This trend may be observed and formulae may be derived based on proportionality of 2 variables (one being controlled at a time)
Why are graphs useful in science?
graphs give a trend of variables and the trend can be studied using the the extent they usually portray and the graphs are not emperical methods they give interpolated relationships hence a reduced uncertainities
Why can't linear graphs give an idea with clothing sizes for infants?
Growth rates of children is not a linear relationship. (The rate of growth changes at different ages).
