Bar graphs can compare two sets of data, as well as line graphs and circle graphs.
To better improve my answer, double line graphs and double bar graphs compare two sets of data. Circle graphs cannot however, because they compare parts of a whole instead of, as a bar graph would, the amount of something. A circle graph is also incapable of showing data growth over a period of time, as line graphs do. All in all, circle graphs cannot compare to sets of data, and bar graphs and line graphs must be doubled to do so.

What are the types of smooth-line graph?
1. PICTORIAL GRAPHS. These are the kind found in mathematics and physics textbooks. Their purpose is to simply and clearly illustrate a mathematical relation. No attempt is made to show data points or errors on such a graph.2. DISPLAY GRAPHS. These present the data from an experiment. They are found in laboratory reports, research journals, and sometimes in textbooks. They show the data points as well as a smooth line representing the mathematical relation.3. COMPUTATIONAL GRAPHS. These are drawn for the purpose of extracting a numerical result from the data. An example is the calculation of the slope of a straight line graph, or its intercepts.
Is it true that in large data sets the mean is always one of the data values?
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
True or false Graphs are representations of equations?
true
Ratio between two sets of measurements?
Oh, dude, the ratio between two sets of measurements is just a way to compare the sizes of things. It's like looking at how many times one thing fits into another. So, if you have, like, 5 apples and 2 oranges, the ratio of apples to oranges would be 5:2. It's just a fancy math term for saying "this many of this, that many of that."
What polygon has 2 sets of parallel lines?
parallelogram
When is a bar graph useful?
when a sets of data can be separated by 2 orders of variables, which are the independent & dependent variables.
What are the Uses of stem and leaf plots?
you use it to compare 2 different sets of data
When do you compare using ratios percents and rates and when do you compare using differences?
when you are specifically comparing 2 sets of data (2 #'s, 2 percents, 2 rates ect.)
What are some advantages of displaying data as a graph?
1. Discovery or identify trends, particularly in time related data 2. Compare sets of data and identify relationships 3. Identifying points that may be erroneous because they are outside of the normal grouping of data. 4. Examine degree of consistency or scattering of data 5. Graphs can effectively communicate ideas/ relationships to others. People can see relationships easier than just looking at numbers.
Is it true that graphs are the only way to interpet data?
It allows you to see a change in the data which you can use to predict a trend or track other noteworthy details. Graphs turn raw data into easy to understand pictures for quick examination.
What is a side-by-side bar graph?
is is when someone makes 2 graphs to compare the diff between in each
What are the disadvantages of a histogram?
Advantages and Disadvantages of HistogramAdvantages:1) Visually strong.2) Can compare to normal curve.3) Usually vertical axis is a frequency count of items falling into each category.Disadvantages:1) Cannot read exact values because data is grouped into categories.2) More difficult to compare two data sets.3) Use only with continuous data.

Explain why bar graphs are useful for comparing data?
so you know the relationship between the 2 variables
Reason for organizing data into frequency distribution?
1. To organize data in a meaningful, intelligible way. 2. To enable the reader to determine the nature or shape of the distribution. 3. To facilitate computational procedures for measures of average and spread. 4. To enable the researcher to draw charts and graphs for the presentation of data. 5. To enable the reader to make comparison among different data sets.
What is a double bar graph used for?
double bar graphs are used for comparing data between 2 different things.
When are scatter plots used?
to show the relationship between 2 sets of data
