Graphs

The slope is therise divided by the run. Or in Cartesian coordinate terms: delta Y / delta X It is how steep the line is. 0 slope is parallel to the X axis. A slope of 1 rises 1 unit Y for every unit X (up and to the right)

you cross the bars out from order from left to right.

The answer is 3 ;)

A line graph can tell you how changes in one variable are related to changes in the other. A line graph cannot show causality. A line graph can show non-linear relationships which some other analytical techniques may not identify. In particular, they are good for identifying relationships between the variables that change over the domain. A line graph can also help identify points where the nature of the relationship changes - eg tension and breaking point, or temperature and phase.

The spread of observations about the "line of best fit" gives a measure of how closely the variables are related and how much of the measurement is systemic or random error.

Time, money, temperature, and numbers.

Independent on the x-axis (horizontal) and dependent on the y-axis (vertical).

A histogram graphs the frequency of how often a specific item falls into a specific category. For instance a histogram would show how many buildings in a city are two, three, four stories, etc... A bar graph compares a specific trait of several candidates. For instance. If you were asked to compare the population of several cities a bar graph would show each cities exact value. a histogram would show how many of the cities fall into different size ranges.

Try this: take a group out to ice cream. How many want sprinkles? how many want chocolate? etc....

you put nothing on the y axis because dis isn't like a coordinate graph

how many people out of 100 like blue green or yellow or out of 100 people wat is there favorite foods

A bar graph is a visual display formed by lines or bars across a scaled grid. The relative lengths of the bars (horizontal or vertical) indicates the values represented.

you can look at the problem...

you see how many spaces there are inbetween the most and least.

then you have to make sure it is the same amount like....

11-19

20-29

30-39

40-49

and on like that.

Sector.

a graph that uses two lines connected by points to show value

The dependent variable is usually plotted on the "y" or ordinal axis.

Exploded pie chart.

Plot different kinds of lines like a dotted or colored line.

/* Vertical Histogram of words in a Sentence */

#include<stdio.h>

}

}

A line graph shows trends over a period of time. Data could include percentages of people who go to Disneyland over ten years, or how many people die of a particular disease each year.

its like a bar graph but with little crosses and you join them up with lines

• they are used for percentages of a whole.

In many cases, histograms help interpretations. But you can probably think of cases where this is not true. Perhaps you have too few values. Perhaps your data has many flaws or errors in it. Sometimes, people will select the data that they want think supports their idea, and make histograms using only this data. See related link on histogram.

Pie graphs are good for showing a percent of something.
