Populations vs. Samples and Random Sampling

Statistics Branch of science that deals with the collection, organization, analysis, interpretation, and presentation of data. Purpose of statistics is to make an inference about a population by examining a sample. Collection of Data Refers to the process of gathering information. Primary source: questionnaires, interviews. Secondary source: journals, books. Presentation of Data Organization and arrangement of data in tabular form (tables), graphical representation (graphs). Analysis of Data Application and interpretation using statistical tools to derive meaning. Inspection of Data Descriptive Statistics: Involves describing the basic features of the data in a study. Provides simple summaries about the sample and measures. Inferential Statistics: Makes judgments and reaches conclusions about populations based on samples. Population vs Sample Population: entirety Sample: only part of population Fundamental or Descriptive Statistics: Measures Of Central Tendency: Mean (average) Median (middle value) Mode (most frequent) Measures Of Dispersion/Variability: Range (difference between highest & lowest) Variance & standard deviation Measures Of Position: Quartiles & percentiles Measures Of Relationship Between Variables: Correlation coefficient Types Of Data: Primary Data – original source. Secondary Data – derived from primary. Major Characteristics Of Data Sources: Primary Source – direct from respondent; more accurate; costly; time-consuming. Secondary Source – characteristic not

Health 11/12 Review for Final Exam Core Concepts - Mental and Emotional Health, Substance Abuse Prevention, Safety and Violence Prevention, Family Life and Human Sexuality, Disease Prevention and Control, Healthy Eating Health Education Skills - goal setting, decision making, accessing information/resources, analyzing influences, communication, self-management, advocacy DIMENSIONS of Wellness - social, spiritual, emotional/mental, environmental, financial, intellectual, multicultural, occupational, physical, sexual RISK factors - anything that increases the risk of disease, injury, or illness. PROTECTIVE factors - anything that decreases the risk of disease, injury, or illness. INTERNAL health factors - health factors that can be either hereditary and genetic or acquired elements -- include smoking and personal diet or eating habits. Example – a genetic predisposition to an illness. EXTERNAL health factors - health factors that are part of the direct outer environment, the geographical location, micro-organisms, socio-economic elements that could affect an individual's health. Example – being unable to afford mental health services. Unit 1- Managing Personal and Community Wellness Explain Maslow’s Hierarchy of Needs in your own words using the image provided. Explain how each Social Determinant of Health may impact a person’s health. Levels of Disease Prevention • PRIMARY The goal is to avoid conditions altogether. • SECONDARY The goal is early detection. • TERTIARY The goal is to minimize the damage (manage). Define the following terms. Fads/Trends Sleep hygiene Driver safety Unit 2- Investigating Social Ecological Factors on Well-Being Socio-Ecological Model – The SEM examines how health behaviors form based on characteristics of individuals, communities, nations and levels in between. Each level overlaps with other levels signifying how the best public health strategies are those that encompass and target a wide range of perspectives. Interpersonal (personal) health vs. intrapersonal (relationship) health Health INEQUITY - systemic, ingrained and unjust barriers that prevent segments of the population from having the opportunity of health leading to health disparity. IMPLICIT BIAS - a form of bias that occurs automatically and unintentionally, that nevertheless affects judgments, decisions, and behaviors. Research has shown implicit bias can contribute to unequal access to quality healthcare, negative patient-provider relationships and interactions; and create mistrust in the healthcare system and practitioners among patients. This can contribute to health disparities. Health DISPARITY - represents a difference in health between populations. It is often used to describe disease burden and other negative health outcomes socially disadvantaged groups may face. Health EQUITY - The opposite of health inequity. It describes a system that supports a high standard of health and healthcare for all people.

Studying population involves examining various aspects of the demographic composition, dynamics, and characteristics of a group of individuals within a specific geographic area. Here are key areas to explore when studying population: Demography: Population Size: Analyze the total number of individuals in a given area or community. Population Distribution: Examine how the population is spread across different regions or areas. Population Density: Explore the concentration of people in a particular area relative to the size of that area. Population Growth and Decline: Birth Rate: Study the number of live births per 1,000 people in a given year. Death Rate: Examine the number of deaths per 1,000 people in a given year. Migration: Explore patterns of people moving into and out of a specific area. Age Structure: Age Distribution: Analyze the distribution of individuals across different age groups in a population. Dependency Ratio: Examine the ratio of dependent individuals (young and elderly) to the working-age population. Gender Composition: Sex Ratio: Study the ratio of males to females in a population. Population Pyramids: Use population pyramids to visualize the age and gender structure of a population. Fertility and Family Planning: Total Fertility Rate (TFR): Explore the average number of children a woman is expected to have during her reproductive years. Contraceptive Use: Analyze the prevalence of contraceptive methods in a population. Mortality and Health: Life Expectancy: Examine the average number of years a person can expect to live. Infant and Child Mortality: Study the number of deaths among infants and children under the age of five. Urbanization: Urban vs. Rural Population: Analyze the distribution of people in urban and rural areas. Rate of Urbanization: Explore the speed at which people are moving from rural to urban areas. Education: Literacy Rates: Examine the percentage of the population that can read and write. Educational Attainment: Study the level of education achieved by individuals within the population. Socioeconomic Factors: Income Distribution: Explore the distribution of income among the population. Employment Rates: Analyze the percentage of the working-age population that is employed. Cultural and Ethnic Composition: Ethnic Diversity: Examine the presence of various ethnic groups within the population. Healthcare and Quality of Life: Access to Healthcare: Study the availability and accessibility of healthcare services. Quality of Life Indicators: Explore factors such as housing, sanitation, and overall living conditions. Population Policies and Government Interventions: Study the impact of government policies on population dynamics, including family planning programs and immigration policies. Environmental Impact: Explore the relationship between population growth and its impact on the environment, including resource consumption and pollution. Global Population Trends: Examine global population trends and their implications, including aging populations and population growth in developing countries. Studying population involves a multidisciplinary approach that incorporates elements from demography, sociology, geography, economics, and public health. Researchers and policymakers use this information to make informed decisions about resource allocation, development planning, and social policies.
