<p>Recently, I searching paper about time series or time course, I found that these two words equally used by researchers. However, time series seems used more wider. wikipedia also use time series (https://en.wikipedia.org/wiki/Time_series). What the difference between these two phrases? Is there any specific context that one phrases more frequently used?</p>

<p>They&#39;re the same thing. You&#39;ll find that there are many words and phrases in English that mean the same thing but happen to be used more in one group than another (e.g., in my original field of study, a &quot;time series analysis&quot; could sometimes be called a &quot;non-stationary analysis&quot;).</p>
