Let us see about the understanding of histograms statistics. Histogram is one kind of statistics graph. The histogram is v one of worldwide setof the graph. The frequency distributions of histograms are matched fora qualitative self-governing variable. Frequency distribution histograms are similar to the bar graph but it has connection between the data values. Frequency distribution histogram graphs are using continuous intervals. These intervals are should be indistinguishable.

The histogram is one of the frequency allocations by means of rectanglebars whose widths specific set periods and whose areas are relative to the matching frequencies. This graph is regularly used to discover the radio frequencies. It is also used to find the mean, median values depend on their highest values. This is the definition of statistics data.

Let us see understanding of histogram graphs.

**Problem 1:**

Draw and understanding the histogram graph for given frequency.

Time period | 1.0-1.5 | 1.5-2.0 | 2.0-2.5 | 2.5-3.0 | 3.0-3.5 | 3.5-4.5 | 4.5-5.0 | 5.0-5.5 | 5.5-6.0 |

Frequency | 1 | 2 | 3 | 4 | 5 | 4 | 3 | 2 | 1 |

**Solution:**

Thegroup of frequencies is demonstrated above. The time periods are indicates in x-axis, and the frequency values are indicates in y-axis. The histogram graph is subsequent below:

This is the understanding of histogram graph for statistics data.

**Example 2:**

Draw and understanding the histogram graph for given frequency.

Radio section | A | B | C | D | E | F | G | H | I |

frequency | 203.5 | 301.7 | 705.77 | 502.8 | 423.4 | 643.2 | 578.6 | 692.4 | 132.8 |

**Solution:**

The group of frequencies is established above. The graph is subsequent below:

This is the graphs of histogram formed by the statistics data.

**Problem 3:**

Draw and understanding the histogram graphs for given data.

Country | Population | Employees | Non employees |

A | 98% | 45% | 53% |

B | 56% | 23% | 23% |

C | 73% | 40% | 33% |

D | 83% | 50% | 33% |

E | 92% | 63% | 29% |

F | 66% | 42% | 23% |

G | 81% | 34% | 47% |

**Solution:**

The collection of dataus is described above. The histogram graph is following below:

This is the graphs of histogram formed by the statistics data.
