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.

How do you draw a smooth curvet through the points of a line graph?
because you have to show your work and make shore its right
The worksheet entries that determine the size of the slices in a pie chart are called the?
Data Series
In a line graph which is the independent variable and which is the dependent variable?
The independent variable is plotted on the horizontal axis, or x axis. The dependent variable, or response variable is plotted on the vertical axis, or y axis.
What does a pie chart represent?
a pie chart represents a subject that all of the subjects have a different percentage.
EXAMPLE: 5% people brush there teeth once a day/ 55% people brush there teeth 2
times a day/ 30% people brush there teeth 3 times a day/ and 10% people
brush there teeth 4 times a day. that all adds up to 100%. a pie chart
has more than one subject. this example has 4 seperate subjects,
all of the 4 little subjects represent a huge subject. the huge subject
is " percentage of people brush their teeth". the italic part represents the 4 little subjects
Is a data table the same as a database?
No. A table is the primary object used within a database to store data. A typical database will consist of many tables.
trend is the increasing or decreasing in a line graph
Example. If u choose to see number of students in a school and they are getting bigger its trend is increasing
How are histograms and bar graphs different?
In a bar graph, the height of the bars is relative to the frequency.
In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"
All graphs need labels or data on both of the axis to be of use. So all graphs require a "key"
How do picture graphs and bar graphs show you patterns over time?
Use the bar graph, if:
Data graph has a negative or zero value.
Has a category label (axis) long.
The following image is an example of this, long labels are easier to read on a bar graph, compared with column charts (column charts).
Which is more useful between bar graph and pictograph?
This is like the chicken and the egg question, which came first. Bar graphs make some information easier to understand, progressions. Pictographs make other information easier to understand, percentages
Does a pie chart illustrate trends?
Generally, pie charts do not indicate trends. Line, bar and column charts are better for trends. They are designed to show how something is split up, so it does not have that purpose, so the answer would normally be no.
However, a pie chart could indicate a trend if there was a pattern in the successive slices, like if each was getting larger and each represented a time period, like a month. A few pie charts shown together could also indicate a trend, by looking at how the same data changes from chart to chart.
What legendary pictographs are in wind waker?
Go to Lenzo and finish his sidequest. Then go up to him and talk to him. Select your pictobox. It will cost 50 rupees.
Advantages of histogram in mathematical term?
I'm not entirely sure what is meant by "mathematical term," but histograms (or bar charts) are frequently used in statistics as a visual representation of the distribution of values in a data set. The advantage is that histograms provide a quick visual check that the assumption of normality has been met. There are also statistical tests for normality, but the accuracy of these tests has been questioned. Histograms, on the other hand, allow you to quickly identify not only normality, but also particular patterns or outliers in the data that may be causing a non-normal distribution.
- another advantage is a it can be useful to identify the distribution of the data
Is a scatter plot the same as a line graph?
A scatter plot is a plot of paired (x,y) data with a horizontal x axis and a vertical y-axis. (definition as given in Elementary Statistics by Triola). Textbooks may have different definitions. If one variable is considered an independent variable, then generally it is the x value. This is particularly important if there is a relationship between the two variables, in that knowing the x value helps predict the y value. A best fit line can be drawn through the points.
A line graph in general connects points on a graph. The x-axis may not be a numerical value or it may not be equal spaced increments. For example, suppose I did surveys in years 2001, 2002 and 2009, counting how many accidents there were in a particular intersection. A line graph would show three years, 2001, 2002 and 2009, as equal spaced intervals on the x-axis.
The above definition is consistent with plots made in Excel. I note that some textbooks may consider a line graph as any plot that contains lines connecting the data.
See related links. You can find many good examples of graphical displays of data on the internet.
In what way are line graphs similar to bar graphs?
They illustrate the relationship between two (or more) variables.
What is an example of an bar graph?
A bar graph looks like a lot of rods, one next to the other, each of different lengths. The length is determined by whatever it is that the graph is measuring. For example, if it's the number of people in a town whose height is between 4'0" and 4'6", and the number whose height is between 4'6" and 5'0", and between 5'0" and 5'6" and between 5'6" and 6'0", then there will be 4 bars in the bar graph, one for each height group.
Which of the cells depicted in the line graph in figure 8-8 are most likely cancerous?
The graph on figure 8-8 is not shown here so there really is not any way to know which one is correct. Without his information the answer is not able to be known.
