Graphs

Because its in the school syllabus

Instead of connecting points with a line, a bar graph uses bars to represent data.

After you have your data, when you record it into the histogram, you make a graph just like a bar graph, only, this time the bars are touching! Does that make sense? Please tell me if i'm wrong!:)

It means that the coordinates of the point of intersection satisfy the equations of both lines. In the case of simultaneous [linear] equations, these coordinates are the solution to the equations.

Technically, neither are better. However, if you are measuring time (example: stocks for a certain company for six months) then a line graph would be better.

Because it shows how much each element of a whole unit takes up. So if you had totals for each of the 12 months of a year, like sales totals, a pie chart would show 12 slices, one for each month. You could then have an indication as to how much each month made up of the total sales for the year. You can get the pie chart to show the actual value of each slice of show the percentage each slice represents of the whole pie.

the scale would be how many units or numbers you go by each line in the line graph.

they both have bars?

The name of the slant on a line graph is called the slope. The slope represents the rate of change between two points on the graph and is calculated by dividing the change in the y-coordinates by the change in the x-coordinates. A positive slope indicates an upward trend, while a negative slope indicates a downward trend.

it depends on what kind of data you are desplaying. if there is only one type of data that is all related and conected, a line graph would be a good thing to use.

it goes on the data table

if you mean as in photographic memory which means when you are able to remember stuff for example....8+9-7+6=16 you might forget that in a second but people with photo graphic memory can remember it forever.

Florence Nightingale Made the pie chart ,also if you watch Horrible Histories On cbbc It tells you that.

With a protractor

if it is a computer generated pie chart, find the fraction, and divide into 360

For the same sorts of uses as they are today : to illustrate how a total value is divided into smaller groups.

A pie chart (a circle divided into slices of various angular widths) is used to show comparative percentages within a whole. The size of a slice is proportional to the share that is assigned to a given subgroup, role, or division. For example, a pie chart for business revenue can be divided into wedges showing the sources of that revenue (sales, stock dividends, franchising), and the sales wedge could be 2/3 or 3/4 of the pie, with other earnings areas having smaller slices.

It can also be called a circular graph

It will be determined by the values that are being represented. All the values together are taken as being the whole pie, and then the slices are allocated according to how much of the total each figure makes.

The most obvious thing is that they look different. A pie chart is circular whereas a bar chart consists of bars of different lengths. A pie chart can only be used for one series of data, to see how each part contributes to the whole thing, by seeing the various pie slices and their sizes as part of the whole pie. Bar charts can consist of more than one series and compare different things to each other and can show trends.

You can label anyting you want on it. For example: there are 22 dogs and 33 cats.

You can compare by seeing where the maximum, minimum, and median are in the histogram s and by also seeing where the histograms cluster at.

A broken bar graph is used when one value, or a few values, goes up very high. Instead of scaling everything down, the abnormally high value is indicated with the broken bar graph. Of course, a number also has to be indicated, so that anybody who reads the bar graph can find out what the number actually is.

class width times frequency density gives you the frequency
