Question: 12 pupils took part within test. There score are:
35, 26, 32, 28, 19, 43, 47, 22, 35, 32, 28, 36
a) Calculate the range of Scores.
b) Caculate the denote score.
c) I sit the test a week beforehand. I scored 27. How do I compare to the close-fisted score.
Answers:
1) scale 19 - 47
b) mean = 31.9 = 32
c) students did 84.375% worse on this check
put all the score in directive - lowest to highest
the breadth is the lowest score to the extreme score, so 19-47
the connote is all the win totals added together, divided by the number of scores, which is 12
compare 27 to the indicate score you own calculated - if 27 is above the mean ranking, you did better, if its below you did worse
A)range = highest - lowest... that's 47 -19 or 28
B)mean = (sum of adjectives scores) / (number of scores)
C) compare 27 to the mean obtain in division b.
do it yourself. This is stupidly easy, lately long and boring. Use excel
the mean is jammy just make the addition of up all of the score and then divide your answer to haw copious scores in attendance is.
Q1 31.9(3sf)
Q2 31.9(3sf)
Q3 85% you qualify
Range 19 to 47. Mean 31.91 You were approx 4 results worse.Mean is the average score.
a) Range = largest - smallest
= 47 - 19
= 28
b) Mean = Total Score / Number of Scores
= 386 / 12
= 32.16 (rounded down = 32)
c) You score lower than the mean smudge... Not sure what else to say here lol!
The sums of the scores is 351 / The average is 29.25.
Your evaluation falls shy of the 50% mark 27 vs 29.25
The lowest win is 19 and the highest is 47 the list (a) therefore is from 19 to 47.
b) The tight (average score) is all score added together divided by 12.
= 383 รท 12 = 31.92
c) You were below average.
a) compass = largest - smallest = 47 - 19 = 28
b) mean = sum of score / 12 = 383 / 12 = 32
c) You scored 27 which is 5 grades below the mean meaning.
Perhaps you must do some extra work in demand to improve your grades in this subject?
Good luck anyway.
a) pinch away the lowest score from the great
b) add up adjectives the scores next divide by the number of scores that in attendance are, in this casing 12.
The range of the ranking is simply the largest score minus the smallest ranking and is 47-19=28.
The mean gain is the average of all the score added together and this is 383/12=31.92.
You are obviously below the miserable score of this small taste, but these students may not be typical.
Range
Bigget number - smallest number
Mean
Add them all up and divide the answer by the number of pupils (12)
Better or worse than the niggardly? You work it out!
