The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right , and whether it is uniform. A graph with a single peak is called unimodal. A single peak over the center is called bell-shaped. And, a graph with two peaks is called bimodal.
How do you describe a graph?
In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner . The points on the graph often represent the relationship between two or more things. ... We then represent the data using a bar graph.
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 determine the shape of a set of data?
We can characterize the shape of a data set by looking at its histogram . First, if the data values seem to pile up into a single “mound”, we say the distribution is unimodal. If there appear to be two “mounds”, we say the distribution is bimodal.
How do you describe a trend in a graph?
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. The trend line is something we add to our graph to make the pattern even clearer.
What is the line on a graph called?
Glossary and Terms: Graphs and Lines. Abscissa – The horizontal line, or x-axis , of a graph. ... Coordinates – A set of two numbers that indicate where a point is on a graph. The first number indicates the x-axis and the second number the y-axis. Other names include ordered pair and numbered pair.
What is a straight line on a graph called?
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 describe the shape of data?
The spread is the range of the data. And, the shape describes the type of graph. The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform . ... A single peak over the center is called bell-shaped.
What is measure of shape?
What is a measure of shape? Measures of shape describe the distribution (or pattern) of the data within a dataset . The distribution shape of quantitative data can be described as there is a logical order to the values, and the ‘low’ and ‘high’ end values on the x-axis of the histogram are able to be identified.
What are the different shapes of histograms?
- Skewed Distribution. The skewed distribution is asymmetrical because a natural limit prevents outcomes on one side. ...
- Double-Peaked or Bimodal. ...
- Plateau or Multimodal Distribution. ...
- Edge Peak Distribution. ...
- Comb Distribution. ...
- Truncated or Heart-Cut Distribution. ...
- Dog Food Distribution.
How do you explain a trend line?
A trendline is a line drawn over pivot highs or under pivot lows to show the prevailing direction of price . Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price, and also describe patterns during periods of price contraction.
How do you explain a trend?
A trend is the general direction in which something is developing or changing over time . A projection is a prediction of future change. Trends and projections are usually illustrated using line graphs in which the horizontal axis represents time.
How do you describe a graph vocabulary?
- 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 are the 6 components of a graph?
- The Title. The title offers a short explanation of what is in your graph. ...
- The Source. The source explains where you found the information that is in your graph. ...
- X-Axis. Bar graphs have an x-axis and a y-axis. ...
- Y-Axis. ...
- The Data. ...
- The Legend.
What are the five basic types of lines?
There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines . Other types of lines are simply variations of the five main ones.
What are the two types of line graph?
There are 3 main types of line graphs in statistics namely, a simple line graph, multiple line graph, and a compound line graph . Each of these graph types has different uses depending on the kind of data that is being evaluated.
