BI 114 Exam 1; Part2
Chapter 3; Tables and graphs
| Term | Definition |
|---|---|
| operculum | a protective covering over the gills in fish |
| gills | an organ (as of a fish) for obtaining oxygen from water |
| gill filaments | what the gills are made of, which serve to increase the surface area; this allows maximum exposure to the oxygen-laden water environment |
| tables | values of the same type are listen down a column instead of across a row |
| tables | only important data are entered (data showing no key differences are often omitted) |
| tables | column headings include units, if needed |
| tables | in a formal scientific report, they are numbered consecutively |
| tables | the title is clear, concise, and shown at the top; it is enough information to stand alone and to be understandable apart from the rest of the report; often the first word and other important words are capitalized; no period |
| tables | can be used when there are large numbers of data points to be displayed, and/or when there is more than one dependent variable to be displayed |
| graphs | accurate and easy to read/understand |
| graphs | can be constructed using graph paper and ruler, or using software, but should no be constructed freestyle by hand |
| graphs | independent variable is typically shown on the x axis and dependent variable is typically shown on the y axis |
| x axis | abscissa |
| y axis | ordinate |
| graph | range is determined so that 'wasted space' is minimal |
| graphs | axes are labeled with appropriate units |
| graphs | title contains enough information to stand alone and to be understandable apart from the rest of the report; only the first word is capitalized; has a period |
| graphs | along with photographs, drawings, and diagrams, these are referred to as a figure (or part of a figure) in a formal scientific report; figures are numbered consecutively through the report |
| graphs | allow someone to visualize the relationship between variables (independent and dependent); this can help in seeing trends in the data that could be difficult to detect otherwise |
| pico (p) | 10 to the negative 12 |
| nano (n) | 10 to the negative 9 |
| micro (mu) | 10 to the negative 6 |
| milli (m) | 10 to the negative 3 |
| centi (c) | 10 to the negative 2 |
| deci (d) | 10 to the negative 1 |
| base unit | 1 |

| length | meter |
| mass | kilogram |
| time | second |
| electric current | ampere |
| thermodynamic temperature | kelvin |
| amount of substance | mole |
