| Term | Definition |
|---|---|
| Accuracy | A description of how close a measurement is to the true value of the quantity measured. |
| Complex Technology | Cars, phones, computers planes, etc |
| Data Table | Tables that hold data that can be used in a graph. |
| Dependent Variable | In a scientific investigation the factor that changes as a result of manipulation of one or more independent variables. |
| Empirical Evidence | the observations measurements and other types of data people gather in tests to support and evaluate scientific explanations |
| Engineering | the application of science and mathematics to solve real life problems |
| Expiriment | an organized procedure to study something under controlled conditions. |
| Graph | A diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles. |
| Prediction | To tell in advance/ for tell the future |
| Quantitative Observation | Relating to information that is expressed by a numbers or quantity |
| Range | the difference between the largest and the smallest number in a data set. |
| Mode | The number or numbers that occur the most frequently in a data set |
| Median | The middle number in an ordered data set with an odd number of data points |
| Bar Graph | A diagram in which the numerical values of variables are represented by the height or length of lines or rectangles of equal width |
| Hypothesis | A testable idea or explanation that leads to scientific investigation |
| Uncontrolled variable | Somthing like a force of nature, size of something, or its phisically unchangeable |
| Histogram | a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval |
| Increments/Intervals | an increase or addition, especially one of a series on a fixed scale. |
| Independent Variable | In a scientific investigation, the factor that is deliberately manipulated |
| Infrence | A conclusion reached on the basis of evidence and reasoning |
| Controlled Variable | In scientific experimentation is the experimental element which is constant and unchanged throughout the course of the investigation. |
| Line Graph | A type of chart which displays information as a series of data points called 'markers' connected by straight line segments |
| Observation | The process of obtaining information by using sentences |
| Pie/Circle Graph | a type of graph in which a circle is divided into sectors that each represent a proportion of the whole |
| Simple technology | Items such as forks, chairs, tables, pencils, etc |
| Precision | The exactness of a measurement |
| Prototype | A test model of a product |
| Pseudoscience | a process of investigation that in one or more ways resembles science but deviates from the scientific methods |
| Metric System | The decimal measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass |
| Qualitative Observation | relating to information that concerns quality or kind |
| Science | The knowledge obtained by observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested |
| T Chart | A chart that shows the independent and the and dependent variable |
| Technology | The application of science for practical purposes ; the use of tools, machines, and processes to meet human needs |
| X axis | The axis on a graph going horizontal; independent variable |
| Y axis | The axis on a graph that is going vertical; dependent variable |
