Welcome back.

In this video I’ll show you which vocabulary to use if you’re describing a trend graph on your task

one essay.

So just to remind you this is what a trend graph looks like.

You can have a trend graph as a line graph as a bar graph or as a table so if you’ll remember we have

a trend graph.

Whenever we have changes that are being described over a certain period of time so this video will only

focus on the vocabulary that you need for describing such trend graphs so when you have a trend graph

These are the types of changes that you’re going to see.

So in this image we have a line graph.

However I want you to note that even if you have a table or a bar graph you will notice similar types

of changes.

So basically you’re going to have any of these seven different types of changes so you may have a data

set where the measurements are increasing the data might experience a big increase or maybe the data

remains constant.

It is also possible that the data might decrease or you may see a big decrease.

You may also notice that sometimes the graph undergoes a decrease but then it improves again.

Lastly the data that you see might go up and down.

This is known as a fluctuation.

So there are particular vocabulary words that you can use to describe each of these different types

of changes so let’s take a look at those vocabulary words.

So first we have increase if you have an info graphic where the data is increasing then you can use

any of these words listed here such as rise climb elevate.

Notice that here we have a verb and in the parentheses we have the noun.

OK so here’s the verb form of the word.

And here’s the noun form of the word.

So for example if you have an info graphic where the data is increasing you could say something like

banana sales grew in 1990.

You can also use the noun form of the word.

So you can say Banana sales experienced a growth in 1990.

OK.

So you can describe this data in both ways.

You can use a verb to describe it or are now to describe it next.

You may have a big increase if you have a big increase then you can use any of these words here such

as Trump surge double and so on.

Here we have the verb.

And here we have the noun.

So you may say something like computer sales doubled in 1990 or you can say computer sales experienced

a doubling in 1990.

Next you may have a decrease.

So if the data is decreasing you can use any of these words here such as fall drop decline here’s the

verb and here’s the noun so you may say something like computer sales dropped by 10 percent you can

also use the noun form so you can say computer sales experienced a 10 percent drop next.

It’s possible that the data might experience a big decrease in such a case.

You can use these words plummet or a plummet tumble or a tumble and so on.

So you can say something like banana sales plummeted in 1990 or you can say Banana sales experienced

a plummet in 1990 next.

It’s possible that the data might remain stable over certain periods of time.

So in these cases you can use these words such as stabilize or stabilization level off or leveling off

and so on.

So you could say Banana sales leveled off in 1990 or you can use this phrase as a noun so you can say

Banana sales experienced a levelling off in 1990.

Now if the data is decreasing but then it starts to improve then you can use these words to describe

this type of change.

You may say something like mobile sales recovered in 1990 or mobile sales experienced a recovery in

1990.

Finally if the data is moving up and down up and down then will we call this a fluctuation.

So you can say Banana sales fluctuated in 1990 or banana sales experienced a fluctuation in 1990 so

these are all the different ways in which you can describe the different types of changes you can describe

the types of changes using the verbs or using the nouns.

Now let’s look at the quality of change when we’re talking about the quality of change.

So let’s take a look so sometimes there may be a slow change in your data whereas other times there

may be a very fast or surprising change in the data.

It’s also possible that there may be a steady change in the data or steady change means that the data

is increasing at a steady rate.

Or it’s possible that the data might be decreasing at a steady rate.

It is also possible that the data remains constant at a steady rate meaning that it does not go up or

down.

On the other hand you can have small changes medium changes or big changes.

So let’s explore the different adjectives and adverbs that we use to describe these different qualities

of changes.

All right.

So here we are.

If you have a fast change then you can use adjectives like rapid sharp quick steep or swift.

You can also use adverbs like rapidly sharply quickly steeply and swiftly.

So if you’re writing a sentence you could say something like there was a sharp rise in computer sales

in 1990 or you can also use adverb to describe the change.

You can say computer sales sharply increased in 1990 if you have a surprising change.

OK an unexpected change then you can use adjectives like sudden striking abrupt or adverbs like strikingly

and abruptly.

So if you’re writing a sentence in which you’re describing a surprising change you may say something

like there was an abrupt rise in banana sales in 1990 or you can say Banana sales abruptly increased

in 1990 so you can describe the quality of changes using the adjectives or the adverbs similarly you

can use these adjectives here on these adverbs here to describe these different qualities of change

including a slow change a steady change a small change a medium change and a big change.

So what you need to do on your task one essay is really quite simple all you need to do is mix and match

So let me give you an example.

So here we have our opening phrase here we have some adjectives here we have the nouns and here we have

the measurement of the data.

So all you need to do is mix and match these different columns.

So here’s an example.

So you can say there was a significant growth in the price of cars notice that to construct this sentence

all we’ve done is used different words and phrases from different columns and we’ve just mixed and matched

So that’s all you need to do depending on what kind of data you have.

All you have to do is choose adjectives from this side and match them with nouns from this side so if

there is a marginal increase then you can say that there was a marginal increase if there was a gradual

decrease.

You can say there was a gradual decrease.

Now let’s look at another example of this.

You can do the same thing with adverbs and verbs.

So here we have our opening phrase here we have our list of adverbs here we have the verbs and here

we have the data points that we’re describing.

So again we’re just mixing and matching the different columns so we can construct a sentence like this

the population marginally declined from 120 thousand to one hundred eighteen thousand two hundred so

notice we’ve used the opening phrase from this column we’ve used the adverb from this column we’ve used

the verb from this column and we’ve chosen to describe the data points in this manner so when you’re

describing these trend graphs you just need to mix and match adverbs and verbs and adjectives and nouns.

So that’s all for this video in the next video I’ll be taking you through the different vocabulary words

that you need to know for describing comparative crafts.

So I’ll see you there.
