Some scholars struggle to analyze and discuss trends in data tables and graphs .



A  trend is a pattern that sustains over time.



You need to identify whether there is a trend for:




Each classification on a bar graph.
























 Each line on a line graph.



























Each category in a time-series collection of pie charts.


























Each category in a time-series data table.
















You should first search for the largest long-term trends when you analyze time-series data sets.


Yo
u may discuss short-term trends if these are the major pattern shown in data.




I suggest that you use this two step approach when analyzing quantitative time-series data.




Step 1: Do you see one or more trends in the data?




Step 2 (a):  Yes



Identify by name one or more trends and discuss them in order of prominence.



Step 2 (b):  No



Discuss volatile (fluctuating) data patterns.




Trends




Flat




Upward trend




Downward trend

No trend


Fluctuation


A discussion example of each trend shall be uploaded on this page during March 2017.
