Maggie and I made this presentation to help you understand the basis of graphing in Biology for your Cambridge exams.

Can you give me an example of some biological investigations in which you could use each one of the four graphs mentioned?

Pay attention as I’m asking you investigations you can carry out in the field of biology, not in general. It must be something related to the topics you are studying in the British curriculum (that is in fact, what your book is based on).

PIE CHART: Showing the percentage of people in a class, which have brown, black, blond or red hair.

Percentage of people working in the primary, secondary or tertiary sector in a place.

BAR GRAPH: number of people who plays an sport in a class.

Number of people saying its favourite colour.

LINE GRAPH: number of inmigrants to a place in different years.

Amonunt of money a family have in different months.

HISTOGRAM: amount of precipitation in different places

Hours of television different children watch.

Hi,

I’m Diego Vegas from 3ºA and this is my reply:

I will use a pie chart if I have to do a representation of different types of job in a city.

I will use a bar graph if I have to do a representation of two or three villages using more or less vehicles, showing the differences between them in the contamination of the ambient.

I will use a line graph if I have to do a representation of how the water evaporates rapidly if you increase its temperature.

I will use a histogram if I have to do a representation of three countries passing through 100 years and showing its population.

Hello, I am going to tell you one example os each graph mentioned.

BAR GRAGH: The precipitation in each month around the year .

-Dependent axe :precipitation in mm

-Independent axe :months of the year

LINE GRAPH: The grow of thenumber of population with a movil phone.

-Dependent axe :number of people with movil phone

-Independent axe:time (years)

PIE GRAPH: How many people work in each economy sector

-Primary ,secondary and tertiary sector

HISTOGRAM: The frequency os age in a population.

-Dependent axe. number of people

-Independent axe :age years( 0-2 years old)

Hello, now I’m going to tell some examples of the four different graphs mentioned.

PIE CHART –> the number of boys and girls that are in class.

BAR CHART –> an investigation of the results of a traffix survey carried out four times a day. In the dependent axe will be the different types of vehicles. In the independent axe will be the diffenrent stages of the the day separated by hours.

LINE GRAPH –> an investigation showing the precipitations along a year. In the dependent axe will be the mL. In the independent axe will be the different seasins of a year (spring, summer, autumn and winter).

HISTOGRAM –> an investigation showing the number of different clothes sold. In the dependent axe will be the different clothes. In the independent axe will be the numbers the sold.

Hello!

PIE CHART: A pie chart can be used to show us, for example, the variety in the diet of a person. the sectors in the pie chart will be carbohydrates, proteins, fats, fibre…

BAR GRAPH: A bar graph can be used to represent the birth rate or death rate of different countries in a year. In the dependent axe will appear the population and in the independent axe will appear the countries. The title can be something as ”Death rate in the countries of the European Union during 2007.” For example.

LINE GRAPH: A line graph can be used to represent the speed of a vehicle. In the dependent axe will appear the space, that the vehicle recorred; in metres, centimetres, kilometres…and in the independent axe will appear the time in seconds, minutes, hours…

HISTOGRAM: Histograms can be used to represent the inmigration of different countries during a period of time. In the depedent axe will appear the population and in the independent axe will appear the years. Each country represented has a bar of a colour. The colours each country has must be explained in a leyend near the histogram.

Andrea Ramos 3ºA.

-BAR GRAPH: The temparature of each month.

-PIE CHART: Percentage of each type of vitamin eaten by a person.

-HISTOGRAM: The frecuency of height of boy in a school

-LINE GRAPH: Population growth

Hello, I’m going again to tell you some examples of the four different types of graphs mentioned. I hope now it’s well done.

PIE CHART –> an investigation in which we can see the portion people eat in a day of each kind of nutrients.

BAR GRAPH –> an investigation showing how many people have each type of blood groups. In the dependent axe will be the blood group (group A, B, AB or either O). In the independent axe will be the percentage of the population who have each type of group.

LINE GRAPH –> an investigation showing how many cigarettes consume each people and specially at what age. In the dependent axe will be the years of smoking ( 20, 20-29, 30-39…). In the independent axe will be the relative risk (the cigarestes they consume).

HISTOGRAM –> an investigation showing the height of people. In the dependent axe will be the height (in meters). In the independent axe will be the number of people.

-Histogram: to classify the people of a group in relation to their weigh.

-Bar graph: to compare the amount of population in different places.

-Line graph: to represent the amount of precipitation in an especific place in a period of time.

-Pie chart: to represent the amount of each type of nutrient we take in.

bar graph:dependent variable-sugars per gram,independent variable-foods

line graph: dependent variable-number of teeth affected by decay per child,independent variable-fluoride content of public water supply/parts per million

pie chart:(in a food) the percentage o sugars,carbohydrates and proteins

histogram:the frequence a heart beats

Paula mateos 3A

PIE CHART: the percentage of each type of food in a diet (carbohydrates, proteins)

BAR GRAPH: A graph showing the time of intervals when the cars arrive a parking> Dependent variable-number of vehicles. Independent variable- time intervals where the car arrives.

LINE GRAPH: A graph showing the ozone levels> Dependent variable- parts per million. Independent variable- months

HISTOGRAM: The precipitations in a place showing in the independent variable the month when it rains and in the dependent variable how many mm.

Elisa Martín 3ºA

Hello! This are my examples of the graphs shown in the video.

PIE CHART: It will appear the amount of different nutrients in a diet of a person: Carbohydrates, proteins, vitamins, lipids…

LINE GRAPH: A line graph can show the maximum speed a bird can reach flying. In the independent axe will appear the time in seconds, minutes, hours… and in the dependent axe, will appear the space recorred.

HISTOGRAM: A histogram can show us the weight of a group of people. In the independent axe will appear the weight in kilograms, from 60kg to 70kg, from 70kg to 80kg, from 80kg to 90kg…and so. And in the dependent axe will appear the number of people: 0, 5, 10, 15, 20…

BAR GRAPH: A bar graph can show us the number of activ hours per weekend at different ages in males and females. In the independent axe will appear the ages. An in the dependent axe will appear the hours. There will be two bars, one for females and other for males, in different colours. The colour each one represent will be explained in a leyend.

Good work Andrea, you really got it!

Just change recorred for covered and this for these:)
