 # Quick Answer: How Do You Analyze A Graph?

## What relationship does the line graph describe?

The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship.

Similarly, the relationship shown by a curved graph is called non-linear..

## How do you read an area graph?

An area chart represents the change in one or more quantities over time. It’s similar to a line graph. In both area charts and line graphs, data points are plotted and then connected by line segments to show the value of a quantity at several different times.

## What is a pattern in a graph?

When you describe patterns on graphs you are describing how the dependent variable changes in relation to the independent variable. Example 1. Time spent training. Skill level at football.

## What does a straight line on a distance time graph mean?

‘Straight lines’ on a distance-time graph tell us that the object is travelling at a constant speed. Note that you can think of a stationary object (not moving) as travelling at a constant speed of 0 m/s. On a distance-time graph, there are no line sloping downwards.

## When should I use a line graph?

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

## What is a trend in a graph example?

A trend line (also called the line of best fit) is a line we add to a graph to show the general direction in which points seem to be going. Think of a “trend” as a pattern in math. Whatever shape you see on a graph or among a group of data points is a trend.

## How do you describe a line graph trend?

Verbs: rise, increase, grow, go up to, climb, boom, peak, fall, decline, decrease, drop, dip, go down, reduce, level up, remain stable, no change, remain steady, stay constant, stay, maintain the same level, crash, collapse, plunge, plummet.

## What do you mean by graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter. Each object in a graph is called a node.

## How do you analyze a bar graph?

Interpret the key results for Bar ChartStep 1: Compare groups. Look for differences in the heights of the bars. The bars show the value for the groups. … Step 2: Compare groups within groups. Compare bars within the clusters to understand the proportions of subcategories within each main group. Compare bars from the same subcategory across clusters.

## How do you write a bar graph analysis?

When analysing bar charts and trend graphs it is good practice to describe what the graph is measuring. If there is no title you should give a description of what the two axes (i.e. the horizontal line and the vertical line) are representing. Range: The difference between the largest value and the smallest value.

## How do you analyze a line graph?

The horizontal label across the bottom and the vertical label along the side tells us what kinds of data is being shown. The horizontal scale across the bottom and the vertical scale along the side tell us how much or how many. The points or dots on the graph represents the x,y coordinates or ordered pairs.

## How do you read a graph?

Graphs have two axes, the lines that run across the bottom and up the side. The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis. The x-axis may contain categories or numbers. You read it from the bottom left of the graph.

## How do you describe the trend of a graph?

TrendsA trend is a pattern in a set of results displayed in a graph.In the graph above, although there is not a straight line increase in figures, overall the trend here is that sales are increasing.In this graph, the trend is that sales are decreasing or dropping.

## What are the three types of trend analysis?

Consumer or market trend analysis can be categorized into three types: geographic, which is analyzing trends within a group that is defined by their geographic location; temporal, or analyzing trends over a specific period of time; and, intuitive, or analyzing trends based on demographic and behavioral patterns and/or …

## What are some common relationships in graphs?

Data correlation. When the data points form a straight line on the graph, the linear relationship between the variables is stronger and the correlation is higher (Figure 2).Positive or direct relationships. … Negative or inverse relationships. … Scattered data points. … Non-linear patterns. … Spread of data. … Outliers.

## What is graph analysis?

Graph analytics is another commonly used term, and it refers specifically to the process of analyzing data in a graph format using data points as nodes and relationships as edges.
