The measure for correlations used is r. We would actually expect the correlation coefficients to be low, since there are so much more to status updates not captured by the word counts. The correlations coloured are statistically significant, though.
...so your observation is correct.
On the other hand, from my own experience, the decisive factors in determining the "popularity" of a status update are
1) real-life popularity of that person (you don't add only virtual "friends", do you?) and
2) that person's tendency to "like" and repeatedly comment on his own status updates
Now I'm no statistician as well and I have no studies to back me up. Duh.
The subject matter, the grade level, the college, the course—these things are irrelevant to me. Prices are determined per page and are based on how long I have to complete the assignment. As long as it doesn't require me to do any math or video-documented animal husbandry, I will write anything.
It's nice to know that our beloved engineering is safe........for now.
Not really. There are engineering courses that do not require maths. From non-technical ones like "Engineers in Society" to technical ones like "Web Security" (of course it can involve maths but you don't need maths to write a paper on web security).
