a) 2, 4, 6, 7, 7, 9, 14
Mean (average):
=
= 7
Median (middle number) : 2, 4, 6, 7, 7, 9, 14 = 7
Mode (most common number): 2, 4, 6, 7, 7, 9, 14 = 7
Midrange (average of smallest & greatest term):
= 8
b) 2, 4, 6, 7, 7, 10, 14
Mean (average):
=
= 7.1
Median (middle number) : 2, 4, 6, 7, 7, 10, 14 = 7
Mode (most common number): 2, 4, 6, 7, 7, 10, 14 = 7
Midrange (average of smallest & greatest term):
= 8
c) the only thing different between part (a) and part (b) is the MEAN
d) 2, 4, 6, 7, 7, 9, 10
Mean (average):
=
= 6.4
Median (middle number) : 2, 4, 6, 7, 7, 9, 10 = 7
Mode (most common number): 2, 4, 6, 7, 7, 9, 10 = 7
Midrange (average of smallest & greatest term):
= 6
The differences between part (a) and part (d) are the MEAN and MIDRANGE
