Data

• Nine per 100,000 of population could be avoided due to causes other than those in the table.
• A histogram shows data from a Scottish study of the proportion of people of different ages with depression who consult their doctor.
• The area of each bar in a histogram is proportional to the frequency of each class interval.
• The independent variable in a histogram is the variable that is divided into sub-sections or classes.
• The rate of death per 100,000 of population due to injury is 3.
• Histograms are similar to bar charts, but show how frequently data occurs within certain ranges.
• The independent variable in an experiment is the variable that is changed, to investigate its effect on the dependent variable.
• The bars of a histogram are next to each other.
• A bar chart shows proportions of cases of cancer in the USA connected with the Human papilloma virus (HPV), and those where no connection has been established.
• The independent variable in the Scottish study is age, but the histogram shows different groups within the variable of range allowing the data to be visually comparable.
• The bars of a histogram may not be the same width - it depends on the range they cover.
• The rate of death per 100,000 of population due to respiratory diseases is 23.
• Health is the state of physical and mental well-being, which is influenced by factors such as genetics, lifestyle, and environment.
• A disease is a disorder that affects an organism's body, organs, tissues or cells.
• Scientists use graphical and statistical methods to analyse patterns of data related to disease.
• Data are often displayed in a graph, which might display trends that are not as clear when just looking at data in a table.
• Bar charts show data collected for separate groups, with the height of the bar being proportional to the measured number or frequency.
• The total number of times an event occurs is represented by the frequency.
• In a bar chart, the bars are all the same width and do not touch each other as they show distinct categories.
• This table of data and bar chart show the number of deaths that could be avoided in England and Wales in 2013 from different causes.
• Cancer is the leading cause of death in England and Wales, with 80 deaths that could be avoided, followed by cardiovascular disease with 62 deaths that could be avoided.
• Drug-related deaths, infections, injuries, respiratory diseases, and other causes of death each contribute to a smaller number of deaths that could be avoided.
