STAT 144 Module 1

• It is a branch of mathematics that focuses on the application of probability theory to statistics. This is the theoretical part of statistics which is concerned with the analysis of random phenomena.


  Mathematical Statistics
• This is an exposition for the statistical methods used in data collection and analysis.


  Statistical Theory
• The development of statistical theory relies heavily on mathematics, particularly, ______.


  Probability
• The term "statistics" is viewed as what two contexts?

  Science and Actual Number
• This deals with methods of organizing, summarizing, and presenting data.


  Descriptive Statistics
• This is concerned with the generalization of the characteristics of a larger set where only a part is examined.

  Inferential Statistics
• Statistics was used in computing the mean number of siblings of UPLB STAT 144 students in the First Semester AY 2022-2023.

  
  

  Is the given problem used statistics as a singular or plural sense?

  Singular Sense
• The total and mean number of siblings are statistics obtained from UPLB STAT 144 students in the First Semester AY 2022-2023.

  
  

  Is the given problem used statistics as a singular or plural sense?


  Plural sense
• The mean number of siblings from the selected UPLB STAT 144 students in the First Semester AY 2022-2023 is two. Is this descriptive or inferential statistics?

  Descriptive Statistics
• Based on the randomly selected STAT 144 students in the First Semester AY 2022-2023, there is sufficient evidence to say that every student in UPLB has two siblings, on the average. Is it descriptive or inferential statistics?

  Inferential Statistics
• It is the description of the essential properties of a phenomenon that is formulated in mathematical terms.

  Abstract Model
• Asking 100 randomly selected UPLB faculty about their job satisfaction rating.

  Is the process describes a deterministic or stochastic model?

  Stochastic
• Rolling a fair die and observing the outcome of the upturned face.

  Is the process describes a deterministic or stochastic model?

  Stochastic
• This model does not permit the formulation of a rule which will determine the precise outcome of an experiment, yet, there is a predictable long-term behavior called statistical regularity.


  Stochastic Model
• Determining whether it snowed in Beijing, China in December last 2019

  Is the process describes a deterministic or stochastic model?

  Deterministic
• Measuring the daily body temperature of a patient infected with coronavirus

  Is the process describes a deterministic or stochastic model?

  Stochastic
• This model describes a phenomenon whose outcome is fixed.

  Deterministic Model
• Computing the mean number of siblings of UPLB STAT 144 students in the First Semester A.Y. 2020-2021

  Is the process describes a deterministic or stochastic model?

  Deterministic
• Other term for stochastic model

  Nondeterministic, random, or statistical model.
