Science bar graphs are the graphs which is used to represent the organized science data in a pictorial form using the **statistical
graphs**. The bar graph are used to demonstrate the organized science data including all science fields. Here we will prepare science bar grpahs that represent the data related to
science fields. Here we will brief about science bar graphs.

Here we will see how the science data are represented using the bar graph.

**Example problem 1- Science bar graphs**

** **

Let us consider the following organised science data given in the table, solve the given science organised data using statistical bar graph.

The human body is made up of huge number of blood cells, they constitute red blood cells, white blood cells, platelets.

The following table shows, the life span of the number of blood cells mentioned above .Solve the organised science data.

Blood cells |
Life span in days |

Red blood cells |
25 |

white blood cells |
50 |

Platelets | 65 |

**Solution:**

** **

The given data can be solved using the statistical bar graphs. The given blood cells types and their life spancan be plotted using the bar graph where the x axis takes the blood cells types and y -axis takes the life span range.

Let us consider the following organised science data given in the table, solve the given science organised data using statistical bar graphs.

A **relative density** of different metals are tabulated as below.Solve the organised science data.

Metals |
Relative density |

copper |
3 |

Aluminium | 5 |

zinc | 4 |

Iron | 8 |

Magnesium | 6 |

**Solution:**

The given data can be solved using the statistical bar graphs. The relative density of metals can be plotted using the bar graph where the x axis takes the metals and y -axis takes the relative density range.
