PROJECT 2
OBJECTIVE
Conduct a survey in your locality to study the prices of various essential commodities Represent the
data using a histogram and estimate the mode
PRINCIPLE
Do you know what are essential commodities? In fact, the goods considered to maintain acceptable
standard of living are called essential commodities
For example, vegetables, fruits, rice, flour, bread, soap, clothes, petrol, etc., are all essential
commodities. The prices of these commodities vary day by day. The prices of these commodities depend
upon their production or (availability) and their consumption.
Generally, we buy the goods of daily use from a nearby shop or from a shopping mall. Nowadays
we do online shopping to buy the goods of daily use.
In this project, the concept of collection and organisation of data and its graphical representation will
be used. We shall represent the collected and organised data as a histogram.
Histogram is a graphical representation of a grouped frequency distribution in the form of rectangles
of equal width, with class-interval as bases and the corresponding frequencies as heights, there being the
gap between any two successive rectangles. We use a histogram to represent groupe data by class-intervals​

Answer 1

Estimated Mode from Grouped Data = 37 & Histogram attached

Step-by-step explanation:

First Raw Data , Price are per pc , per kg , per litre etc as applicable

Cauliflower       40

Lady Finger     30

Sunflower oil   100

Petrol               70

Diesel               60

Tomato            30

Onion               40

Potato              10

Rice                  60

Orange            40

Bananas           40

Bread               30

Apple               70

Guavava          50

Mode = 40  max 4 times without grouped data

Classes           Freq

5  - 25               1  

25 - 45              7

45 - 65              3

65 -85               2

85 - 105             1

Mode =  25  +   20 *  ( 7 - 1) /( 7 - 1 + 7 - 3)

= 25 + 20  * 6 / 10

= 25 + 12

= 37

Estimated Mode from Grouped Data = 37
