Skill Needed For a Data Science Career
The Career in Data Science is a steep learning curve, and you need to master mathematical and statistical computations and interpersonal and communication skills. Mathematical and Statistical skills are required for a Data Scientist to understand the techniques behind Machine Learning algorithms on how and when to use the algorithms.
Top Mathematical Skills required for Data Scientist
Mathematical Skills are essential in Data Science to perform analysis and discover insights from data. Data Scientists require mathematical skills to understand Machine Learning algorithms to perform and identify the insights from data. Understanding and identifying the business challenges and transforming them into mathematical statements is one of the significant steps in the Data Science workflow.
The following are the top Mathematical skills required for Data Scientist
1. Linear Algebra : Linear Algebra helps to build the linear equations of the Machine Learning algorithm and is further used to examine the data sets. Matrix algebra is used in everything from Facebook friend suggestions to turning your selfie into a Salvador Dali-style painting utilizing deep transfer learning.
Neural networks, which are machine learning models inspired by the human brain, are also driven by the matrix. It helps to identify the molecular gasses, and in the future, the neural networks can be used as security in airports to identify illegal chemicals and drugs.
2. Calculus : Calculus is a study of the continuous rate of change in the slope and the area of the curve. It is an integral part of the analysis in statistics that helps to understand the relationship between tangents and curves. Calculus also feeds the logistic regression algorithms similar to linear regression algorithms and predicts a probability value. The gradient descent model in Calculus is also used to calculate the required value from the data sets.
The two methods of Calculus are used in Data Science to analyze and derive a value from the available data sets.
- Differential Calculus helps to divide something into small pieces to find the changes and helps to analyze more.
- Integral Calculus helps combine the small pieces to find how much it is.
3. Geometry : Geometry helps measure an object’s size, shape, and position in terms of area, length, and volume using a compass, set square, and protractor. Modern Data Science uses Geometry and topological techniques to identify the structural features of data sets.
4. Arithmetic : Arithmetic is a study of numbers used to calculate addition, subtraction, multiplication, and division. In Data Science, Arithmetic is a part of logarithms, especially the Binary Search Algorithm used in programming for debugging.
The Binary search algorithm uses logarithms to search quickly and helps to reduce the time by completing the task in a precise way. The algorithm can identify where the bug occurs instead of searching the entire chunk of code.
5. Probability : Probability theory is the core concept that explains many methods in data science. It helps to increase the chances of outcomes to occur and helps to analyze to choose a better way to increase the probability of outcome occurrence.
6. Bayes Theorem : Bayes Theorem is one of the essential concepts of probability theory used in Data Science. It determines the conditional probability of an event, and this conditional probability is known as a hypothesis.
Top Statistical Skills required for a Data Scientist
Statistics is used to analyze complex problems by Data Scientists and derive meaningful insights from data with mathematical computations. Various Statistical principles, functions, and algorithms analyze the data to identify the outcomes.
The following are the two main categories of Statistics used in Data Science.
1. Descriptive Statistics: Descriptive Statistics helps prioritize the data and characterizes it based on the required parameters.
Descriptive Analysis has been done by creating histograms, graphs, line diagrams, etc., based on central tendency measures such as Mean, Median, Mode, Variance, and Standard Deviation.
- Mean: Mean is the average of the available values in the sample data sets.
- Median: Median is a central value of the sample data sets.
- Mode: Mode is the recurrent value in the sample data sets.
- Variance: Variance is the range of random variables that differ from the expected value
- Standard Deviation: Standard deviation measures the distribution of sample data set from its mean.
2. Inferential Statistics: Inferential Statistics helps generalize the data sets and allows the application of probability to derive the best outcomes. Data scientists can use the inferred parameters based on the sample statistics in the data sets.
Inferential Analysis includes hypothesis testing to test whether enough evidence in the sample data to infer a specific condition holds true for the entire population. By taking random samples of data sets, we analyze the properties to understand the characteristics of the data.
