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.

In a data table how do you know the independent varble?
You would know because it would be the only one thet changed,hence the indepndent concept.
A line graph can mislead when the numbers that they graph goes up by are small so it seems like it goes up a lot but really, it isn't improving.
Give you an example of a histogram?
This is the definition of a histogram: A histogram is a graph showing the intervals and frequencies of a certain topic. That's about all I can give you, because I don't know how to make graphs on here. SORRY!!

In a line graph each pair of numbers expresses a relationship between two what?
Quantities, measurements. For example, distance and time, volts and amperes, days worked and salary earned, etc — any two quantities in a linear relationship.
How can i draw a line graph to represent a car traveling at twice a speed?
i dont think you can use a line graph for that. i think a table would be better...
How do you find the slope on a line graph?
Y-intercept Form From the formula y = mx + b
The y-coordinate of a point on the line equals the product of the slope of the line and the corresponding x-coordinate plus the y-intercept (the vertical line that runs through the point).
y - b = mx
m = y-b/x
Coordinate Points
The slope of a line can be seen visually and computed from the change between coordinates: the distance along the Y-axis divided by the distance along the X-axis, also known as the "rise over run." You can find the slope by finding whole-number coordinates for points that the line passes through. For a straight line, the slope of any segment is the slope of the line as a whole.
The formula is m= Δy/Δx
or m = (y1 - y2) / (x1 - x2)
- Find the Y-difference between the two points by subtracting the second from the first.
- Find the X-difference between the two points by subtracting the second from the first.
- Divide the Y-change by the X-change (one or both may be negative)
The slope will be the Y-change divided by the X-change. It is a positive slope for an upward slanting line, and a negative slope for a downward slanting line, as seen moving from left to right.
Rise over Run
The process is the same, except that you subtract the leftmost, lower X value from the larger X value to create a positive "run" number. Then you subtract the Y value of the leftmost point from the Y value of the rightmost point, giving you a "rise" that may be positive or negative.
Examples:
1) Finding the slope for a line that runs through the points (2,1) and (5,7). Start at the leftmost point and move right until you reach the other point. In this case, you should move across 3 spaces. So 3 is your "run." At the same time you are moving right, the Y value increases from 1 to 7. This is 6 and is your "rise."
Divide the Y-change by the X-change, rise over run, to get 6/3 or a slope of +2.
2) Finding the slope for a line that runs through the points (2,1) and (4, -3). Start at the leftmost point and move right until you reach the other point. In this case, you should move across 2 spaces. So 2 is your "run." At the same time you are moving right, the Y value decreases from 1 to -3. This is a drop of 4, or a "rise" (fall) of -4.
Divide the Y-change by the X-change, rise over run, to get -4/2 or a slope of -2.
As above, an upward slanting line has a positive slope, and a downward slanting line has a negative slope.
What fraction of a pie graph is 30 degrees?
Since a complete circle is 360 degrees, a 30-degree part of a circle is 30/360, or 1/12, of the pie.
A pictograph is a graph containing picture.

How is a box plot and a histogram alike?
Both plots are ways of visualizing data. Both are used in statistical analyses. But I would say they are not very alike. Histograms show the relative or absolute frequency of data in specified (usually equal) intervals. The range of values in a single data set can be seen on a histogram. A box shows how the median and range of various datasets vary over time (or some other variable).
What are the differences between Pie Chart and a histogram with merits and demerits?
i think the major defrince in calculation pie chart use degree by converting percent but histogram use frequncy and class mark umm and in their drawing style
What does a double broken line graph look like?
A double broken line graph features two distinct lines plotted on the same set of axes, each representing different data sets. The lines are typically broken or segmented to indicate changes or discontinuities in the data. Each line can differ in color or style to help differentiate the two data sets, and points on the lines may represent specific values at given intervals. This type of graph is useful for comparing trends or patterns across the two data sets over the same time frame or category.
What is a line graph and description of line graph?
a line graph is where you plot out your answers. you put dots next to each other by 1 inch and draw a line to each dot so you see if something is better or worse than before.
What is a line graph used for in science?
Line graphs can be used for many things in Science. One of the uses are comparing statistics from two different time periods. For example: Climate in 2007 compared to climate in 1907. (This is just an example)
Difference between line and bar graphs and pictographs?
bar graphs use bars and pictographs use pictures
