What is Hypothesis

 What is a Hypothesis in this Hypothetical World? Hypothesis: A hypothesis is an explanation for an observed problem or phenomenon based on previous knowledge or observations. Often called a research question, a hypothesis is basically an idea that must be put to the test.       Research questions should lead to clear, testable predictions. The more specific these predictions are, the easier it is to reduce the number of ways in which the results could be explained. Some problems require a fair amount of information and knowledge before one can formulate useful hypotheses, particularly if the problems are complex in nature. Characteristics of hypothesis: Hypothesis must possess the following characteristics: Hypothesis should be clear and precise. If the hypothesis is not clear and precise, the inferences drawn on its basis cannot be taken as reliable. Hypothesis should be capable of being tested. In a swamp of untestable hypotheses,  many a time the resear...

Data Science and Machine Learning

  Basic Concepts of Data Science and Machine Learning  Data Science is the extraction and analysis of the relevant information from Data. Machine Learning  is the part of Data Science, which enables the system to process datasets autonomously without any human interference by utilizing various algorithms to work on the massive volume of data generated and extracted from numerous sources.  Benefits: Data Science Helps in finding and refining target viewers  Ensure better communication between service providers and service utilizers. Improved business value and better risk analysis.  Machine Learning Supportive in marketing and predicting accurate sales forecasts Helpful inaccurate medical diagnoses Supportive in the elimination of data duplication and erroneousness Caring in spam detection Provide appropriate product recommendation Required Expertise Data Science  Programming Skills Data Warehousing  Statistics Mathematics Software Engineering Dat...
