Make Individual series,Discrete series or Frequency Array and Continous
series or Frequency distribution with the help of a table(series)containing
figures.
Answers
Answer:
where is figure?????????????????????
Answer:
It is series that deals with discrete variables. It is the series in which data are presented in a way that exact measurement of units of the items or terms are shown clearly.
If we are to prepare discrete series from individual series or raw data, it is better to place values in ascending order, then against these variables we put tally bar for each item against the corresponding variable, then number of total tally bars is counted and a numerical number is put in 3rd column as frequency.
EXAMPLE:
ADVERTISEMENTS:
Weight of 20 students of a class is given as following. Prepare discrete frequency distribution (In kgs.) 37, 39, 43, 47, 39, 43, 37, 39, 43, 43, 39, 4 7. 43, 43, 39, 39, 43, 47, 47, 43.
Solution:
We put in ascending order first.
37, 37, 39, 39, 39, 39, 39, 39, 43, 43, 43, 43, 43, 43, 43, 43, 47, 47, 47, 47.
We find that there are only four variables i.e. 37, 39, 43, 47.
Continuous Series:
It is the series that deals with continuous variable. It is such a series in which items may or may not be exactly measured. They all are used within limits. Here even fractional values can be placed in corresponding class intervals. Here class intervals are taken instead of the variable and tally bars are put against these intervals. Then frequency is calculated from tally bars.
EXAMPLE. Marks of a class of 50 students are given as following.
Construct continuous series with intervals 0-20. 20-40…… 80- 100.
21, 3, 47, 42, 24, 0, 27, 59, 68, 37, 78, 11, 33, 79, 41, 29, 39, 54, 46, 82, 44, 30, 49, 51, 84, 54, 47, 51, 30, 56, 61, 66, 51, 32, 67, 71, 57, 50, 37, 61, 76, 81, 71, 58, 68, 87, 99, 77, 70.
