Term | Definition |
---|---|
Complex Technology | Phones, Computers, Planes. |
Accuarcy | a description of how close a measurement is to the true value of the quantity measured. |
Data Table | A shortcut for calculating multiple results in one operation and a way to view and compare the results of all the different variations together |
Dependent Variable | in a scientific investigation, the factor that changes as the result of the manipulation of one or more independent variables. |
Empirical Evedence | the observations, measurement, and other types of data that people gather and test to support and evaluate scientific explanations. |
Engineering | The application of science and mathematics to solve real-life problems. |
Experiment | An organized procedure to study something under controlled conditions. |
Graph | Visual aid use by scientists to communicate results |
Prediction | Indicate in advance on the basis of observation, experience or scientific reason. |
Quantitative Observation | relating to the information that is expressed by number or quantity. |
Qualitative Observation | Relating to information that concerns quality or kind. |
Range | The difference between the lowest and highest values. |
Mode | The number which appears most often in a set of numbers. |
Median | The middle number in a sorted list of numbers. |
Bar Graph | Used to display data and compare data that are separate. |
Hypothises | A statement predicting the result of a controlled scientific experiment. |
Uncontrolled Variable | The variable that cant be controlled. Ex: Wind knocking an experiment over |
Histogram | A type of bar graph the also shows the frequency of data within equal intervals. They use bars instead of Xs |
Increments/ Intervals | An increase or addition, especially one of a series on a fixed scale. |
Independent Variable | A variable that is manipulated to determine the value of a dependent variables. |
Inference | A conclusion reached on the basis of evidence and reasoning |
Controlled Variable | The one element that is not changed throughout an experiment. |
Line Graph | Shows continuous data, or data that can take any form, shown a line. |
Observation | The process of obtaining information by using senses. |
Pie/Circle Graph | A graphic representation of quantitative information by means of a circle divided into sectors. |
Simple Technology | Spoon, Chair, Table |
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 method. |
Metric System | A way to measure that all of the world uses. |
Qualitive 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 that can be verified or tested. |
T Chart | A chart with cells that on the left side has Independent Variable and on the right side Dependent Variable. AKA Data table |
Technology | The applications of science for practical purposes, the use of tools, machines, materials, and process to meet human needs. |
X axis | On a graph measuring the dependent variable |
Y axis | On a graph, measuring the independent variable. |
Mean | The average or sum of all the values in a data divided by the number of items in a data set. |
