Many technical, scientific and other documentation involves data in the form of graphs and diagrams, along with text. If you aspire to get into the world of science, engineering, architecture or other similar careers, you will need to know all about data. Not only how to present data, but how to read and understand it too. Data handling also involves ranges and averages. The range of data is the difference between the highest and lowest frequencies. There are three different types of average - mean, median and mode. Median is the middle frequency piece of data, mode is the one that appears...

If you aspire to get into the world of science, engineering, architecture or other similar careers, you will need to know all about data. Not only how to present data, but how to read and understand it too. Data handling also involves ranges and averages. The range of data is the difference between the highest and lowest frequencies. There are three different types of average - mean, median and mode. Median is the middle frequency piece of data, mode is the one that appears most often and mean is worked out by adding all the frequencies together and dividing by the number of frequencies. Collecting data and recording it in diagrams, graphs tables and charts helps us to organize and understand the data we have collected. We call this interpreting data. Knowing which data to record in which diagrams or charts is important in order for your audience to understand your findings. A survey on vehicles might use a pictogram showing cars and trucks for example, or a survey on favorite colors might display its findings in a colored pie chart. Show less
