How do you write a description of a graph?

How do you write a description of a graph?

For most graphs, give a brief description including the title and axis labels and mention trends not already described in the text. For simple charts, state the actual data points. For more complex charts, an ideal description would include the data in a table or list.

How do you summarize a line graph?

Use precise vocabulary like steadily declined and a sharp increase to describe trends. Use linking expressions like while and in contrast to make comparisons. The question asks you only to ‘Summarise the information’. Don’t give reasons why these trends might have occurred, or your personal preferences on the topic.

What are 5 ways to describe a graph?

Describing language of a graph

• UP: increase / rise / grow / went up / soar / double / multiply / climb / exceed /
• DOWN: decrease / drop / fall / decline / plummet / halve / depreciate / plunge.
• UP & DOWN: fluctuate / undulated / dip /
• SAME: stable (stabilised) / levelled off / remained constant or steady / consistent.

What do line graphs tell us?

A line graph is commonly used to display change over time as a series of data points connected by straight line segments on two axes. Line graphs are useful in that they show data variables and trends very clearly and can help to make predictions about the results of data not yet recorded.

What does it mean to analyze a graph?

By Mara Pesacreta. A graph is a diagram that is meant to represent data and to portray a relationship. Analyzing graphs is useful for determining the general trend, relating the results of an experiment to the hypothesis and for formulating hypotheses for future experiments.

How do you describe a line graph that goes up and down?

Line graphs usually describe trends or changes. With these, it is quite common to use different words to describe increases or decreases. You can also describe the graph staying the same using the verb phrases ‘remain unchanged’ or ‘remain constant’. Small changes up and down are called ‘fluctuations’.

How do you analyze a bar graph?

Interpret the key results for Bar Chart

1. Step 1: Compare groups. Look for differences in the heights of the bars. The bars show the value for the groups.
2. 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 read histograms?

How to read the histogram. A histogram is a graphical representation of the pixels in your image. The left side of the graph represents the blacks or shadows, the right side represents the highlights or bright areas, and the middle section represents the midtones (middle or 18% gray).

What is the line on a graph called?

Glossary and Terms: Graphs and Lines. Abscissa – The horizontal line, or x-axis, of a graph. Axis – One of the lines that is used to form a graph. There is the horizontal x-axis and the vertical y-axis in a two dimensional graph.

What does a straight horizontal line on a graph mean?

A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!

What is the formula for a curved line?

Other Curved Lines To find the equation for a non-parabolic, non-quadratic line, students can isolate points on the graph and plug them into the formula y = mx+b, in which m is the slope of the line and b is the y-intercept.

What kind of function is a curved line?

The graph of a non-linear function is a curved line. A curved line is a line whose direction constantly changes. A cautionary note: Economists are accustomed to designate all lines in graphs as curves – both straight lines and lines which are actually curved.

Is a straight vertical line a function?

if you can draw any vertical line that intersects more than one point on the relationship, then it is not a function. This is based on the fact that a vertical line is a constant value of x, so if there is one input, x, with more than two outputs, y, then it breaks the function rule.

How do you determine if something is a function?

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

What is the rule of a function?

A function rule describes how to convert an input value (x) into an output value (y) for a given function. An example of a function rule is f(x) = x^2 + 3.

What is a function rule for a table?

A function table has values of input and output and a function rule. In the function rule, if we plug in different values for the input, we get corresponding values of output. There is always a pattern in the way input values x and the output values y are related which is given by the function rule.

How do you describe a function?

DESCRIBING FUNCTIONS

• Step 1 : To describe whether function represented by the equation is linear or non linear, let us graph the given equation.
• Step 2 : Graph the ordered pairs.
• Step 3 : Describe the relationship between x and y.
• Step 1 :
• Step 2 : Graph the ordered pairs.
• Step 3 : Describe the relationship between x and y.

How do you describe the behavior of a graph?

The end behavior of a function f describes the behavior of the graph of the function at the “ends” of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).
