Our world today is run by data. The amount of data we produce each day is 2.5 quintillion bytes, with a population of 7.8 billion. In the process of digital transformation, data is the primary resource to perform analysis. Organizations have realized the necessity for evolving from a knowing organization to a learning organization. Commercial industries are widely using techniques and technologies of data analytics to have rational business decisions. Data analysis requires descriptive statistics to help you make better business decisions from data.
What is Statistics?
Statistics is the collection, analysis, and interpretation of knowledge. Statistics is a fundamental tool of data scientists, who are expected to gather and analyze large amounts of structured and unstructured data and report on their findings. Following are the two main statistical methods used in data analytics:
- Descriptive statistics
It is the process of using and analyzing the quantitatively describes or summarizes features from a collection of information. These summaries form the idea of the initial description of the info as a part of a more extensive statistical analysis.
- Inferential statistics
Statistical inference is that the process of using data analysis to infer properties of an underlying distribution of probability. Inferential statistical analysis speculate properties of a population. It is assumed that the observed data set is sampled from a bigger population. In machine learning, the term inference means to make a prediction, by evaluating an already trained model.
What is Analytics?
Analytics is the process of extraction of meaningful patterns in data. Core computer programming, statistics and machine learning are the concrete base for Analytics, to provide quantifiable performance and prediction. Analytics results in data visualization of trends and metrics to communicate insight. Firms may commonly apply analytics to business data to explain, predict, and improve business performance. Specifically, arenas within analytics include predictive analytics, enterprise decision management, retail analytics, web analytics, sales department sizing and optimization, price and promotion modeling, credit risk analysis, and fraud analytics. Analytics requires extensive computation and statistics for their algorithms to produce trends.
Types of Data Analytics.
Four basic types of data analytics.
1. Descriptive analytics is the evaluation over a given period of time. What is the rating of channel this week? Does it increase? Are the sales pump up with new marketing strategy this month?
2. Diagnostic analytics investigate the cause of change. This requires hypothesizing heterogeneous data. How weather affect the clothing series? Did the sales pump up with new marketing strategy?
3. Predictive analytics forecasts what could be happen in near time. What was happened last time when we overdue client? How many t-shirts sale in winter this year?
4. Prescriptive analytics suggests a set of actions and measures. if the summer weather How weather expends for more than 4 months, we have to increase the production of t-shirts this summer.
Statistics in Data Analytics
In Analytics assumptions are made upon the trends and predictions are made relying upon the statistics. Statistics focuses on analyzing, collecting, and interpreting data in a logical and usually numerical way, it makes sense that the techniques developed in Statistics are directly useful within Data Analytics. Analytics helps you form hypotheses, while statistics allow you to test them.
Analytics helps you form hypotheses. It improves the quality of the questions. Statistics helps you test hypotheses. It improves the quality of the answers.
Statistics and Analytics in today’s era of Data
1. Social Media and Analytics There are 4.7 billion internet users. Companies like Netflix, Facebook, YouTube, and Instagram all have their algorithms which works on statistics of its consumer. Data analytics shows the company what the customer prefer watching, and it gives the content accordingly.
2. Data Analytics for Business Risk Management Data analytics widely contribute to the development of providing solution for risk management. With the availability and highly diverse statistics, data analytics amplifies the quality of models for risk management. Consequently, businesses can have smarter strategies and can make deliberate decisions.
3. Data statistics in Supply Chain Management
It offers supplier networks with greater accuracy, clarity, and Insights. Through the application of data analytics, suppliers achieve contextual intelligence across the supply chains. Basically, through data analytics suppliers can escape the constraints faced earlier.
4. Statistics of Weather Patterns
Nowadays weather sensors and satellites are deployed all around the globe. A huge amount of knowledge is collected from them, then this data is employed to watch the weather and environmental conditions. All the statistics is used in weather forecasting, to study global warming, in understanding the patterns of natural disasters. Deep Thunder is an IBM research project, which provides weather forecasting through high-performance computing of big data. They are also serving Tokyo with ameliorate weather forecasting for natural disasters with predicting the probability of damaged power lines.
5. Analytics in transportation and deliveries
Data statistics has been used in various ways to make transportation more efficient and easier. Following are some real life examples.
Route planning: Analytics estimate users’ needs of different routes depending upon their transportation mode to plan the routes with minimal halts.
Congestion management and traffic control: Using statistics, real-time estimation of congestion and traffic patterns is now possible. For examples, people are using Google Maps to locate the smallest amount traffic prone routes. Uber generates and uses an enormous amount of knowledge regarding drivers, their vehicles, locations, every trip from every vehicle, etc. All this data is analyzed and then used to predict supply, demand, and location of drivers, and fares that will be set for every trip. Several top logistic companies like DHL and FedEx are using data analysis to look at collected data and improve their overall efficiency. Using data analytics applications, the businesses were ready to find the simplest shipping routes, delivery time, also because the most cost-efficient transport means.
Statistics is employed to realize deeper and more fine grained insights into how exactly our data is structured and supported that structure how we will optimally apply other data science techniques to get even more information, Which is processed in Analytics. The focus of analytics is to mine data, discover meaningful patterns in data and based on the findings, derive actionable insights, and communicate them to executives. Data analytics examines and draw conclusions about the information they contain.
