Technology is not just a part of our life, it is making our life much better. Data is almost available everywhere and we create an enormous amount of data in our day-to-day life. Its all about the 1’s and 0’s which we create and it is almost present everywhere.

For example: When we use an AI Toothbrush, we create an enormous amount of data. This toothbrush carry a enormous amount of data and can study our brushing patterns and time we brush.

To be in short,this AI toothbrush know better about your tooth than you know about it.It suggest you…


Tree map is a hierarchical map made up of nested rectangles frequently used in business Intelligence which helps organizations to understand the data hierarchically. The tree map was invented in the early 1990s by Ben Shneiderman at University of Maryland College Park.

To construct a tree map we need the following:

  • The Data should be hierarchical with several levels.
  • The size of Rectangle and color are used for describing or differentiating the characteristics of the data.

The above is the Treemap figure the top 15 countries which would be producing the total percentage of mismanaged plastic waste in the year…


In our day-to-day life we come across many problems in which we have certain problems that revolves around choosing a category such as pass/fail, win/lose, alive/dead ,healthy/sick ,Yes/No, etc. It’s like picking up a single choice out of two choice. Decision making plays an important role in our life and selecting any of the choice has its own consequences.

By reading the above stuff’s, you may dwell with the question whether to proceed with this blog or skip it?

Make a Choice.

Come on lets dive in assuming that you have chosen the YES Category. It was a good choice…


A Stem and Leaf Plot is a frequency diagram in which raw data is split into two parts(stem and leaf) and then displayed. It is used to display quantitative data.

A stem and Leaf plot almost resembles an inverted Histogram with an added advantage of displaying all the data points in the Dataset.


Box and Whisker Plot is a graphical representation that can be used to understand the measures of spread, variability, skewness and the existence of outliers in quantitative(numerical) data. Generally it is also known as the graphical representation of the 5-point summary .(Minimum,Maximum,median,25th percentile & 75th percentile)

The diagram that shows all possible logical relations between a finite collection of different sets is known as Venn Diagram or Set Diagram.


A histogram is an approximate representation of the distribution of numerical (continuous)data. It was first introduced by Karl Pearson. Histograms are used to see the distribution of the data and estimating the probability density function of the underlying variable.

  • It helps to identify the measures of central tendency( median ,mean and mode)
  • It helps to identify the measures of spread.
  • It helps in find the skewness and determine the shape of the Distribution namely Left-Skewed, Right-Skewed or Symmetric Distribution.

Histogram vs Bar Plot


Scatter Plot is a plot of two variables that is used to understand if there is any relationship between two variables. The relationship can be linear or non-linear. It is also used to identify the outliers.

Relationship between culmen_length_mm variable and body_mass_g variable from penguin dataset

We could see the random dots but what relationship can we see?


This is the first-ever Pandemic that the Humankind have acknowledged in the Digital age because we are tackling this pandemic with Internet and other technological advancements that we have never done before. Just think how would this pandemic would have been if we don’t have an access to internet.
