Time Correlation

Recently, I have been analyzing the amount of time individual students spend on Khan Academy.  As I expected, there is a definite positive relationship between their grade and the time the student spends on Khan.

Looking at the overall time spent watching the videos and practice problems on Khan, the students with the most time spent have a higher grade.  If I look at the students earning A’s in the class, their time spent is on average much higher than a student earning a lower grade.  In fact, the time and most of the grades directly correlate.

When I look at the time of day that a student does their homework on Khan, it correlates with their grade.  It seems that students doing their homework in the morning before class are earning lower grades.  For example,  I have students that are doing their homework at 7:45 a.m when class begins at 8:15.  It seems to reason, they are not completely absorbing the material by rushing through before the bell rings.

In conclusion, I would probably find the same results correlating time spent on homework with grades in a traditional style classroom.  However, now I have data to provide me with information to help guide students to be more productive.

  1. What it is attempting to say is that repetitive sound uncorrelated (genuinely irregular, inferring a zero connection time) while genuine clamor is not really arbitrary and has an example to it that rehashes in limited time. So the connection time it is alluding to is the measure of time for the sign to "rehash" in a factual sense

    I don't see an unwinding time in the quote you put in your inquiry. Be that as it may, an unwinding time is normally the measure of time it produces for a non-harmony results to achieve balance (for instance, the time it takes for introductory unsettling influences to vanish in a vibrating framework leaving just the constrained reaction, or the measure of time it would take for vitality to move between modes in a gas flow connection). What it is likely discussing is if the measure of time it takes for the framework's reaction to clamor, all things considered, is longer than the connection time of the genuine commotion, you can utilize background noise a sufficient estimate to the genuine sign.
