What is the difference between aerage and range control charts versus histograms?

Control Charts are the graph used to study how the process changes over time whereas histogram is frequency distribution shows how often each different value in a set of data occurs( Histogram is not related to time directly).

How would you use a line graph to make predictions?

To use a line graph to make predictions, you have to look at the slope of the line. If there is any sort of pattern to the line, you can make an accurate prediction. For example, if the line steadily dropped, then suddenly spiked down, then started steadily dropping again, you could predict from the pattern that it will suddenly spike downward again.

What is the difference between a line graph and broken line graph?

a broken line graph has numbres going everywhere and a line graph has numbers going on a steady rate (e.g 50,10,90 for a broken line graph) (eg 2,4,6 for a line graph) hope i helped :D

What is the difference between a pictograph and a tally table?

A tally chart does not show pictures. A pictograph shows you pictures.

How histogram is used in peer to peer system when connected using star topology?

Histograms are typically not used for anything other than looking at patterns of network traffic; it has little or nothing to do with topology or peer to peer systems as is.

Why do scientists use graphs and data tables?

Scientists use graphs and data tables to organize and derive information from the data. It starts with the data table. The table organizes all the information that the scientist has collected into one place that can be easily moved around, added to and deleted from. A graph can then be created using the data from the table. The graph is just a visual representation of the numbers in the table. It is often much easier to find patterns, cause and effect or whatever answers the question that the scientists isattempting to answer.

Although data tables themselves can hold any and all information, it is usually best to minimize the number of comparisons in a graph. Otherwise your graph can be more confusing than the raw data.

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

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?

What is a line graph trend?

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"
