What is the importance of statistics in modern economic set up? explain giving examples.
classify the following data by taking class intervals such that their mid-values are 17,22,27,32 and so on:30, 30, 36, 33, 42, 27, 22, 41, 42, 30, 30, 21, 54, 36 ,31, 16, 40, 28, 19, 17, 48, 28,48, 36, 14, 37, 16, 37, 17, 54, 42, 41, 51, 44, 32, 46, 42, 31, 21, 47, 25, 36, 22, 52, 41, 40, 40, 53.
The frequency distribution of two variables is known as
(a) Univariate Distribution
(b) Bivariate Distribution
(c) Multivariate Distribution
(d) None of the above
Students of class XI obtained following marks in economics.- 15, 15, 18, 16, 20, 21, 25, 25, 16, 18, 22, 24, 25, 20, 18, 22, 24, 24, 25, 23, 20, 15, 16, 17, 19, 18, 22, 22.
classify the data in the form of individual series, discrete series, continuious series and cumulative frequency series.
how will you choose the wants to be satisfied
difference between discrete and
continuous variable
in examination 25 students secured marks

49 52 53 54 56 56 58 61 62 65 68 arrange these data in form of frequency distribution usingclass as intervals
20-29 30-39 40-49 50-59 60-69 aarange the data in cumulative frequency
How many classes should we have? How does one decide about the size of class interval?
