Why are measurements and observations displayed in tables? | When they are displayed in tables they are more understandable and easier to read. |
What can Spreadsheets be programmed to do? | Spreadsheets can automatically calculate values ; averages . |
Define the word discrete from discrete groupings? | Discrete groupings are observations that can be sorted into definite categories and counted. |
Define the word continuous? | Measurements involving numbers aren't discrete but continuous. This means that if you choose two numbers you can always find other numbers in between. |
What are some examples of continuous measurements? | Examples of continuous measurements include age, mass, length, volume, temperature and human height. |
Discrete groupings can construct different types of graphs name them. | Discrete groupings can only construct pie or sector graphs. |
Line graphs require two sets of measurements that show continuous variation. What are they? | The two sets of measurements are the horizontal and vertical axes. |
What's the difference between line graphs and lines of best fit? | Line graphs connect trough different points and lines of best fit go roughly through all the points. |
What do Scientists need to do during an experiment to make it useful? | Scientists need to a scientific report to explain how they ran the experiment, what they measured and how they interpreted the results. |
How do tables and graphs help scientists when they do their experiments? | Tables and graphs help scientists display patterns in their measurements. |
What types of graphs are used when you have a set of discrete observations? | Bar and column graphs show discrete values . |
What is shown in a pie or sector graph? | A pie or sector graph shows proportions of each grouping within an total. The whole pie or sector graph represents 100%. |
What are the different types of line graphs? | Line of best fit and curve of best fit. |
What can a graph do that table cannot? | A graph can show trends more clearly than tables can. |
What makes an experiment complete? | An experiment will be complete when using some way or another you communicate with other scientists. |
What computer program can enable you produce a digital table or a spreadsheet? | A spreadsheet can enable you to produce computer programs such as Microsoft and excel e.t.c.. |
Apart from enabling computer programs what else can a spreadsheet do? | A spreadsheet can also use scientist's measurements to construct different types of graphs. |
When discrete groups are categorized are measurements possible between each of the categories? | No measurements are possible between each of the categories. |
Bar and column graphs have discrete values, but what is displayed from the graphs? | The discrete values display the horizontal and vertical axes on the graphs. |
Once you have plotted all the points on a line graph there are two ways to connect the points. What are they? | They two ways are curve of best fit and line of best fit. |
