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.

6. Dashboard

7. Report

8. Statistics

9. Diagnostic Analytics Focus: causes of outcomes. Methods: data mining, correlation, root cause analysis. Example: Analyzing why website traffic dropped in June.

10. Predictive Analytics Focus: forecasting future outcomes. Uses machine learning & statistical models. Example: Predicting customer churn for a telecom company.

11. Prescriptive Analytics Focus: suggesting best course of action. Tools: optimization, simulation, AI. Example: Recommending best pricing strategy for profit.

12. Introduction to Quantitative Reasoning Definition: ability to use math & logic to solve real-world problems. Involves interpreting numbers, graphs, and data. Essential in business, science, and daily life.

13. Why Quantitative Reasoning Matters? Improves critical thinking and problem-solving skills. Supports data-driven decisions. Reduces bias and reliance on assumptions. Example: Evaluating investment options using ROI.

14. Applications of Quantitative Reasoning Business: ROI analysis, financial planning. Healthcare: risk assessment, treatment outcomes. Education: evaluating student performance. Daily life: budgeting or interpreting news data.

15. Summary Computing & Analytics transform data into insights. Four types of analytics: Descriptive, Diagnostic, Predictive, Prescriptive. Quantitative reasoning is essential for logical, data-driven decisions.

16. Q & A Any Questions? Thank you for your attention!

17. Quantitative Reasoning Measure The Quantitiative reasoning measure assess:

18. General Problem Solving Steps

19. Step 1: Understand the 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

20. For example Find the 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

21. Step 2: Carry out 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

22. Step 3: Check your answer After evaluating the result, it is necessary to 1. check the answers relevancy 2. check for its truthfulness 3. check for its reasonability

23. Solving Arithmetic Problems Numbers BODMAS Rule Solving fractions Solving Decimals Percentage Rounding off Exponents Radicals

39. Example

40. Example Which of the following could be the units digit of 63 n , where n is a positive integer? Indicate all such digits.

41. Strategy 13: Determine Whether a Conclusion Follows from the Information Given, a method for logical reasoning and critical thinking. Strategy Overview: This strategy addresses problems where you are presented with information and a potential conclusion, and you need to ascertain if the conclusion logically results from the given information
