Term | Definition |
---|---|

Graphs | a diagram representing a system of connections or interrelations among two or more things by a number of distinctive dots, lines, bars, etc. |

Horizontal Axis | a reference axis, usually horizontal, of a graph or two- or three-dimensional Cartesian coordinate system along which the x-coordinate is measured. x-axis in Science |

Vertical Axis | Also called axis of ordinates. The axis, usually vertical, along which the ordinate is measured and from which the abscissa is measured |

Origin | The 0,0 point on a line graph, the point where the x-axis and y-axis cross on a graph. |

Coordinate | A pair of numbers used to determine the position of a point on a graph |

Data Point | A point on a graph showing the location of a peice of data. |

Line of best fit | A smooth line that reflects the general pattern in a graph |

Linear Graph | A line graph in which the data point yield a straight line |

Slope | The steepness of a line on a line graph, equal to its vertical chang divided by its horizontal change. |

Non-linear graph | A graph in which the data points do not fall in a straight line |

Science | The study of the natural world through observations and logical reasoning |

observing | the process of using one or more sense |

inferring | The process of making an inference an interpretation based on observations |

predicting | the process of forecasting what will happen in the future |

chemistry | the studies of properties of matterand how it changes |

physics | the study of matter, energy, motion, and forces and how they react. |

scientific inquiry | the ongoing process of discovery in science |

hypothesis | a possible explanation for a set of observations and an answer to a scientific question |

parameter | a factor that can be measured in an experiment |

manipulated variable | the one variable that a scientist changes |

responding variable | variables that change due to the manipulated variable |
