- 1. Introduction to Computing& Analytics Types of Analytics & Quantitative Reasoning
- 2. What is Computing& Analytics? • Computing = using computers to process & manage data. • Analytics = systematic use of data to generate insights. • Helps in decision-making, problem- solving, and innovation.
- 3. Importance of Analytics •Transforms raw data into useful information. • Supports evidence-based decisions. • Improves efficiency & competitiveness. • Example: Healthcare analytics improving patient care.
- 4. Types of Analytics •Descriptive Analytics – What happened? • Diagnostic Analytics – Why did it happen? • Predictive Analytics – What will happen? • Prescriptive Analytics – What should we do?
- 5. Descriptive Analytics • Focus:past data, summarizing trends and patterns. • Tools: dashboards, reports, statistics. • Example: Monthly sales report showing revenue trends.

- 9. Diagnostic Analytics • Focus:causes of outcomes. • Methods: data mining, correlation, root cause analysis. • Example: Analyzing why website traffic dropped in June.
- 11. Predictive Analytics • Focus:forecasting future outcomes. • Uses machine learning & statistical models. • Example: Predicting customer churn for a telecom company.
- 13. Prescriptive Analytics • Focus:suggesting best course of action. • Tools: optimization, simulation, AI. • Example: Recommending best pricing strategy for profit.
- 15. Introduction to QuantitativeReasoning • Definition: ability to use math & logic to solve real-world problems. • Involves interpreting numbers, graphs, and data. • Essential in business, science, and daily life.
- 16. Why Quantitative ReasoningMatters? • Improves critical thinking and problem- solving skills. • Supports data-driven decisions. • Reduces bias and reliance on assumptions. • Example: Evaluating investment options using ROI.
- 17. Applications of QuantitativeReasoning • Business: ROI analysis, financial planning. • Healthcare: risk assessment, treatment outcomes. • Education: evaluating student performance. • Daily life: budgeting or interpreting news data.
- 18. Summary • Computing &Analytics transform data into insights. • Four types of analytics: Descriptive, Diagnostic, Predictive, Prescriptive. • Quantitative reasoning is essential for logical, data-driven decisions.

- 20. Quantitative Reasoning Measure TheQuantitiative reasoning measure assess:
- 21.
- 22. Step 1: Understandthe Problem • Whether the question is numeric or in words? • Identify the given quantities • Identify the quantities to be find • in which form the answer is to be present
- 23. For example • Findthe final result in? 2 x (5 + 8 - 9) / 4 - 1 a. First identify the type of question b. Identify the technique to be used to solve it c. Identify the output form
- 24. Step 2: Carryout a strategy for solving the problem Developing a strategy to solve a mathematics problem is more than identify the • given information • conditions and • facts because a single question may be solve using different techniques
- 25. Step 3: Checkyour answer After evaluating the result, it is necessary to 1. check the answers relevancy 2. check for its truthfulness 3. check for its reasonability
- 26. Solving Arithmetic Problems •Numbers • BODMAS Rule • Solving fractions • Solving Decimals • Percentage • Rounding off • Exponents • Radicals
