Study Notes

Introduction to MATH Class

  • The presentation welcomes students to a math class.

Probability and Statistics in Daily Life

  • This section focuses on probability and statistics in daily life.
  • The presentation is prepared by Vherline A. Doronin, LPT, Instructor I.

Objectives

  • Explain basic probability concepts and data collection methods.
  • Recognize the importance of probability and statistical analysis in daily life decision-making.
  • Collect and analyze data, perform statistical calculations, and use results to evaluate risks and support decision-making.

Basic Concept of Probability

  • Probability is a branch of mathematics dealing with the likelihood or chance of events occurring.
  • Probabilities are expressed as numbers between 0 and 1, where 0 represents impossibility and 1 represents certainty.
  • A probability of 0 means the event will not occur.
  • A probability of 1 means the event will certainly occur.
  • A probability of 0.5 suggests an equal chance of the event occurring or not occurring.
  • Examples include rolling a 5 on a six-sided die (probability of event occurring is likely to be 1/6) or flipping a coin and getting heads (likely to be 1/2).

Statistics

  • The word "statistics" comes from the Latin word "status," meaning a science pertaining to data collection, analysis, interpretation, and presentation.

Data Collection and Analysis

  • Data collection is a systematic process to gather information to answer research questions or test hypotheses.
  • Data types include:
    • Quantitative: numerical data (e.g., height, weight, scores)
    • Qualitative: descriptive and categorical data (e.g., colors, names, types of objects)
  • Data collection methods include:
    • Surveys and questionnaires (for large groups)
    • Interviews (in-depth exploration, but prone to interviewer bias)
    • Experiments (controlled environments to observe effects)
    • Observational studies (observing and recording without manipulation)
    • Secondary data (using existing data from other sources)

Data Analysis

  • Data analysis involves analyzing collected data to obtain meaningful insights.
  • Steps include:
    • Data cleaning (addressing missing, incomplete, or inconsistent data)
    • Descriptive statistics (summarizing data with measures like mean, median, mode, range, variance, standard deviation)
    • Inferential statistics (making predictions or inferences about a population from a sample)
    • Visualization (using graphs like histograms, bar charts, scatter plots to identify patterns)

Application in Risk Assessment and Decision Making

  • Probability and statistics play a crucial role in assessing and mitigating risks in various areas:
    • Financial Risk (evaluating investment opportunities, assessing creditworthiness, managing portfolio risk)
    • Operational Risk (identifying and mitigating potential disruptions like supply chain or technology failures)
    • Environmental Risk (assessing potential impacts of environmental factors on business operations, like climate change or natural disasters)

Informed Decision Making

  • Probability and statistics provide a framework to move beyond intuition and make informed decisions.
  • Risk management involves using these techniques to assess, evaluate potential risks, and develop mitigation strategies.
  • Strategic planning relies on using probability and statistics to predict future trends, analyze market opportunities, and develop effective plans.
  • Continuous improvement uses data analysis to monitor performance, identify areas for improvement, and continually refine processes.

Conclusion

  • The presentation concludes with a thank you.
