Describe how to identify a trend and a relationship between sets of graphed data
1 answer:
Trends are simply the patterns on a graph.
The types of trend are:
- <em>Linear trend</em>
- <em>Nonlinear trend</em>
- <em>Random trend</em>
<em />
<u>The linear trend</u>
This is identified in any of the following ways
- <em>An increment in a variable causes an increment in the other variable</em>
- <em>An increment in a variable causes a decrement in the other variable</em>
<em />
Any of the two stated above represents a linear trend
<u>Nonlinear trend</u>
This type of trend are in form of curves
When you observe that the pattern on the graph follows a curve, then the trend is nonlinear
<u />
<u>Random trend</u>
This simply means no trend or scattered trend.
When there are no visible relationship between the variables of the graph, then the graph has a random trend.
