Question

create a grouped frequecy distribution attached is the graph

Answer 1

i believe grouped frequecy and relative frequency amount to the same ...

Answer 2

yeah, i believe we create classes and assign the number of times a count occurs to a class; by convention, there are abt 5 classes

Answer 3

123
456
789
101112
131415

now we assign the number of times a count appears in the ranges we picked

it would appear that the structure could be:

class freq
---- ------
1-3 2/8
4-6 3/8
7-9 1/8
10-12 1/8
11-15 1/8

the "/8" part im unsure about tho; cant recall if we include it or not :)

Answer 4

from a cursory look at the google; the "grouped" table excludes the "/8" bits
