hey there
welcome back how are things going
i know that you are great because you
are young
and full of positive energy spread your
positive energy among the people around
you
because it is very important to stay
positive
in this worse situation due to covid-19.
anyway now come to the discussion in our
previous lesson
we have been discussing about bar chart
in this lesson we are going to discuss
about pie chart in details so
what is a pie chart a pie chart is a
statistical graphic which is divided
into slices
to illustrate numerical portions pie
chart are
very widely used in the business world
and mass media. Use pie chart
to compare the proportion of data
in each category a pie chart is a
circle that is divided into segments
or slices to represent the proportions
of observations
that are in each category
to interpret a pie chart that you get in
your board exam
or your ssc exam or your hsc exam
you have to compare them in groups you
can see that
when you interpret one pie chart
look for differences in the size of the
slices
the size of slice shows the proportion
of observation
that are in that group
when you compare multiple pie charts
look for
differences in the size of slices for
the same categories in
all the pie charts
however look at to this pie chart
this chart is about population of
countries of the European union in 2007
by percentage so look at to this diagram
so this red portion indicates to germany
16.6 the population of germany is 16.6
so this blue portion indicates to
France 12.8 percent population
France belong to 12.8 percent population
this yellow portion indicates to united
kingdom and this
orange portion indicates to Italy
maroon indicates to Poland and this gray
portion indicates to
all other countries pie chart normally
show proportion
which can be measured in percentages or
productions
this chart shows the relative size of
populations
of countries of the European union in
2007.
so we can only make comparisons
we cannot say anything about change
we can see that the country with the
largest population was
Germany with 16.6 percent of the
European union's population we can also
see that
the second largest population was that
of France with 12.8 percent
of the population we do not
know from this chart which country has
the smallest population
because the 21 smallest countries are
included in one group if you are
interested
then i'm telling you it is Malta
with less than 0.1 percent
you can see that the four largest
countries like Germany France
the united kingdom and Italy together
make up more than
half of the European union's population
you cannot say that
Poland has the smallest population 21
other countries have population smaller
than poland's
the 21 smallest countries of the
European union
make up nearly 30 percent of the
populations
so what have we understood by reading
these analysis
so look at to this first
section so here we can see the
introduction this is the introductory
paragraph of this
analysis here you can see the message of
the diagram
and finally you can see the conclusion
okay
from this analysis we can find some
important points
so look at to this point use of tenses
mind the correct use of tenses when
describing a chart
if the charts deals with facts in the
present
as in our example use the simple present
if the facts are the past
then use simple past if there is a
connection between the past and present
then use
present perfect
so how to describe a chart with
following example
we would like to show you how charts are
described
mind the three parts and do not repeat
the global message
in the conclusion right
so first you have to maintain
introduction here
you see that the diagram is about
mind title of it and do not forget
to include the source okay then you have
to write down
the message of the diagram and after
that
finally you have to write down the
conclusion so these three parts are
much more important in analyzing a
graph chart or pie chart
list with paraphases to describe charts
if you want to describe the chart you
can use
some phrases like this the pie chart is
about the bar chart deals with the line
graph clearly shows
okay you can use these phrases to
explain or to analyze
pie chart right
so here you have a question
so let's read it out in a survey for
northern ireland
teen time magazine 100 teenagers were
asked the question
do you do anything else while you are
watching tv
the pie chart below shows the results of
the survey
summarize the information in the chart
by selecting
and reporting the main features and
make comparisons where relevant
so you can see that only one person
of the teenagers read while watching tv
two percent of them listen to music
while watching tv
and three percent of them do exercise
eight percent of the teenagers talk to
their family members while watching tv
eight percent of them do homework 23
percent
of the teenagers watch tv and do
nothing else 28 percent of the teenagers
have breakfast lunch or dinner while
watching tv
and 27 percent of them
use mobile phone or tablet right
so here you have some tips for
for writing analysis for this pie chart
so number one start by saying exactly
what the pie chart shows
number two the second sentence in the
introduction
should summarize the single most
important thing
from the chart number three the
second paragraph describe the survey
results
in more detail use a variety of language
to describe
proportions fractions and
percentages use expressions for
comparing like while however and so on
in the conclusion summarize the bigger
picture and mention the most
significant percentages or trends
okay let's try to write it down
this pie chart shows teenagers answers
to a survey
for northern Ireland teen time magazine
which asks them if they do anything else
while they watch
tv it can be seen that over three
quarters of those
survey do other things
simultaneously over half said
they either ate or checked their mobile
phone or
tablet while they were watching tv
while perhaps surprisingly
only a few teenagers said they read
did exercise or listen to music while
watching tv
eight percent talked to their families
and another eight person
said they often did homework and watched
tv at the same time it is not
clear from the pie chart if they did
more than
one additional activity at once in
conclusion
it is evident that a large proportion of
families
watch tv while they are eating
while almost a third young people divide
their attention between several
screens at the same time
these figures may reflect a general
trend towards
less formal family meal times and
greater
levels of multitasking however
a significant number of teenagers still
focus
fully on the television when they are
watching in these analysis
we can see that the pie chart
starts by saying exactly what the pie
chart shows
you see
this pie chart shows teenagers answers
to a survey
of northern Ireland teen time magazine
which asked them
if they do anything else while they
watch
tv in the second sentence in the
introduction
the single most important thing was
summarized
from the chart you see it can be seen
that
over three quarters of those surveyed
do other things simultaneously the
second paragraph described the survey
results in more detail
and also we have used variety of
languages
to describe proportion fractions and
percentages you see
we used expressions here also we used
expression
for comparing while however etc
right in the conclusion
we have just summarized the bigger
picture
and mentioned the most significant
percentages
and trends
so here we have another question the pie
chart below illustrates
how internet users 16 plus
prefer to access the internet at home
and in another places summarize the
information in the pie chart
by selecting and reporting the main
features
okay on a desktop computer it is 14
percent
on a tablet 19 percent okay
30 percent on a laptop and 33 percent on
a
smartphone four person is used in other
devices
top tips for writing number one start by
saying exactly what the pie chart shows
avoid copying words in the question use
other words with the same or
similar meanings number two mention the
survey question
what participants answer explain
what the different sections of the pie
chart
refer to describe the key findings
shown in the chart let's try to write it
down
this graph shows the results of a survey
in which people aged 16 and over were
asked about their preferred devices for
accessing the internet the question
referred to
going online at home and in other places
participants mentioned four main devices
in their answers a smartphone a laptop
a tablet or a desktop computer
from the pie chart it is clear that the
majority of participants
prefer to use smartphones and laptops
with just three percent difference
between the two
nearly a third of participants prefer to
go
online with a smartphone 30 percent
like to use a laptop a desktop computer
accounts for 14 percent
of users preferred devices
only a small minority prefer
a device other than this main form
in conclusion since mobile and portable
devices
are in the most popular choices it is
clear that
many participants are accessing in the
internet
outside their homes the desktop computer
is the
least computer of the four main and
more people accessing the internet with
smartphones
and their preferred choice so how
we analyzed this pie chart
at first we have started by saying
exactly what the pie chart shows
secondly we have mentioned survey
question
thirdly we have explained the different
sections
of the pie chart okay we have
also described the key finding
this lesson will not be effective as it
is supposed to be
if you don't practice so
here's a home task given for you try to
do it
by yourself and submit it to the comment
box
in our next lesson
we will focus on phrase and clause
try to go through to this lesson
this is the end of today's lesson take
care stay home
stay safe thanks a lot
