ALGEBRA. EQUATIONS FIND N.
I'm not sure what the first "N" signifies. If it signifies another score, depending on its value, it could change the other values. If it is the highest score, it would change the range. If is is the same as any of the previous scores, it would detemine the mode. Can you see what I mean?
The mode is the most frequently occurring score. there doesn't seem to be any mode in your distribution.
The mean is obtained by adding all the scores and dividing by the number of scores. I assume that you can do the calculations.
The median is the 50th percentile (50% of the scores are above that value and 50% are below. Thus, with an even number of scores, your median would be between 14 and 15 (14.5).
I hope this helps. Thanks for asking.
