I've heard many different things from many different people. Can seasonal trends ONLY be applied for data that represents a period of one year or less? What are the differences between seasonal and cyclical trends and how can I differentiate between the two? :s

Seasonal and cyclical variations

Yeah I've read that but I've also heard from teachers and students that seasonal trends can also be over a period of one year if the differences between the peaks remain the same or something. :\

To be honest, I never really went in depth into that stuff, early in the year I had a pretty terrible understanding of Core, but what they said sounds good, unfortunately I cannot clarify.

I thought if differences between peaks is the same its seasonal.
From maths quest:
"seasonal trends have a fixed and regular period of time between one peak and the next peak in the data values."

This is from A+ further notes
Seasonal: The time series graph shows a pattern what repeats at regular intervals.
Cyclic: The graph shows a pattern that repeats but at irregular intervals and with differing intensity.

so many retards dont get the two meanings of period;
its been getting used as in the period of a circular function, thus how often a variation will repeated itself
and then its also used as "over the period of one year"
cyclical variations repeat themselves every year or more
seasonal variations repeat themselves more frequently than a year

forgeth the retards bit that was harsh
