Lecture#03
we will discuss the frequency distribution of a non-stop variable & the graphical methods of
representing statistics relating a continuous variable i.e. Histogram, frequency polygon and
frequency curve. You will consider that during Lecture No. 1, it was mentioned that
a continuous variable takes values over a non-stop c language (e.g.
A regular Pakistani adult male’s height may additionally lie everywhere between five.25 ft and
6.5 feet).
Hence, in any such situation, the approach of building a frequency distribution is
somewhat distinctive from the only that became discussed inside the final lecture.
EXAMPLE:
Suppose that the Environmental Protection Agency of a advanced u . S . performs large checks on
all new car fashions a good way to determine their mileage rating. Suppose that the following 30
measurements are received via conducting such checks on a specific new automobile model.
EPA MILEAGE RATINGS ON 30 CARS
(MILES PER GALLON)
36.three 42.1 44.nine
30.1 37.5 32.nine
40.five forty.0 forty.2
36.2 35.6 35.9
38.5 38.eight 38.6
36.3 38.four 40.5
41.zero 39.zero 37.0
37.zero 36.7 37.1
37.1 34.8 33.9
39.nine 38.1 39.eight
Document Summary
Lecture#03 we will discuss the frequency distribution of a non-stop variable & the graphical methods of representing statistics relating a continuous variable i. e. histogram, frequency polygon and frequency curve. 1, it was mentioned that a continuous variable takes values over a non-stop c language (e. g. a regular pakistani adult male"s height may additionally lie everywhere between five. 25 ft and. Hence, in any such situation, the approach of building a frequency distribution is somewhat distinctive from the only that became discussed inside the final lecture. Suppose that the environmental protection agency of a advanced u . S . performs large checks on all new car fashions a good way to determine their mileage rating. Suppose that the following 30 measurements are received via conducting such checks on a specific new automobile model. Epa mileage ratings on 30 cars (miles per gallon) There are a few steps in the production of a frequency distribution for this sort of a variable.
