Data Type

1. Explain the difference(s) between the 2 diagrams.

2. What is the difference between discrete and continuous data?

3. What is the relationship between Histogram and continuous data?


  1. Q1: There are spacings between the rectangular blocks in the bar graph whereas there are none in the histogram. The bar graph represents discrete data but the histogram represents continuous data. The bar graph also has categories; e.g. USA, India, etc. but the histogram only shows a range of numbers for one specific category.

    Q2: Discrete data is more specific but continuous data shows a range of numbers.

    Q3: Histograms' bars are connected, thus allowing it to represent continuous data over a range of numbers.

  2. 1.
    - While the bar graph has a gap between the bars, the histogram does not.
    - While the histogram has a range of numbers, there are categories in in bar graph which only displays one type of information.

    2. Discrete data is straight to the point and specific (integers) while continuous data is a range of numbers.

    3. Histogram represents a continuous data set so there are no gaps in the data as there are numbers in a range to indicate data that flows.

  3. 1. Differences:
    Bar Graph:
    There are gaps between the graphs
    It is a discrete
    There are no gaps between the graphs

    2. Discrete datas is meant to represent datas that are in whole numbers while Continuous data can be used to represent datas in decimal and whole numbers.

    3. Can be used to represent range of answer which is in continuos figures and can use it to compare figures.

  4. 1. Visual: The bar chart has gaps while the histogram has no gaps.
    Data: The numbers in the bar graph are fixed, while the numbers in the histogram is a range of numbers.
    2. Discrete data can be counted, while continuous data can be measured.
    3. Continuous data is used in histograms and both are used to present a range of numbers, so there are no gaps in the histogram.
