72
= 103475 / 72
= 1437,152

5. The middle value when we list the data
from smallest to the largest.
 We have a 72 person
 The number of SMS 36.person = 1200
 The number of SMS 37.person = 1200
MEDİAN = 1200 + 1200 / 2 = 1200

6. The value that has the highest
frequency = 6
VALUE FREQUENCY
500 6
1000 4
1500 1
2000 0
2500 1
3000 1
3500 1
4000 1
4500 2

7. Measure of dispersion
Average = 2250
VALUE Xi - Xaverage (Xi – Xaverage)²
500 -1750 3062500
1000 -1250 1562500
1500 -750 562500
2000 -250 62500
2500 +250 62500
3000 +750 562500
3500 +1250 1562500
4000 +1750 3062500
4500 +2250 5062500
2250 0 20525000
s² = 20525000 / 8 = 2565625 (25625625)½ = 1061,756
For some value
for the measure
dispersion…
