Census
Chapter 1 of 11
🔒 Unlock Audio Chapter

Chapter Content
A comprehensive survey covering every single member of a population.
Detailed Explanation
A census is an extensive and detailed survey conducted to gather information about every individual in a particular population. This means that unlike regular surveys, where only a sample of people is asked questions, a census aims to include everyone without exception. The data collected can help governments allocate resources, plan for services, or understand demographic changes over time.
Examples & Analogies
Think of a census like taking attendance in a classroom; just as a teacher records the name of every student present to understand who is in class and plan for lessons accordingly, a census records every person in a country to help the government understand its population.
Genealogy
Chapter 2 of 11

Chapter Content
An extended family tree outlining familial relations across generations.
Detailed Explanation
Genealogy refers to the study of family lineages and the relationships among family members. A genealogy chart visually represents these relationships, usually showing grandparents, parents, children, and often extending further back. This method is often used in sociology and anthropology to understand social structures and familial ties within communities.
Examples & Analogies
Imagine creating a family tree for your family history, where you draw lines connecting parents to their children and extend the branches back to grandparents and great-grandparents. This tree not only illustrates your family connections but also helps understand the roles and responsibilities among members.
Non-sampling Error
Chapter 3 of 11
🔒 Unlock Audio Chapter

Chapter Content
Errors in survey results due to mistakes in the design or application of methods.
Detailed Explanation
Non-sampling errors occur when the results of a survey are affected by factors other than the actual sampling process. This can include errors in how questions are worded, misunderstandings by respondents, or mistakes in data collection. Unlike sampling errors that can arise simply from studying a part of the population rather than the whole, non-sampling errors typically result from flaws in the research design.
Examples & Analogies
Consider a scenario where a teacher gives a test, but some questions are confusing or poorly worded. If students misinterpret these questions and answer incorrectly, the test results won't accurately reflect what the students know. This is akin to non-sampling error in a survey.
Population
Chapter 4 of 11
🔒 Unlock Audio Chapter
Sign up and enroll to access the full audio experience
Chapter Content
In the statistical sense, the larger body (of persons, villages, households, etc.) from which a sample is drawn.
Detailed Explanation
The term 'population' in research refers to the entire group that researchers are interested in studying. This is the full set from which a smaller sample is selected for analysis. Understanding the characteristics of the population helps ensure that the findings from the sample can be generalized back to that larger group.
Examples & Analogies
Think of a population like a jar of mixed candies. If you're told to figure out the average amount of red candies without counting them all, you might scoop out a handful (the sample) and assume the rest of the jar has similar proportions of red. If your handful is representative, your conclusions about the entire jar will be accurate.
Probability
Chapter 5 of 11
🔒 Unlock Audio Chapter
Sign up and enroll to access the full audio experience
Chapter Content
The likelihood or odds of an event occurring (in the statistical sense).
Detailed Explanation
Probability is a mathematical concept that measures the likelihood of a particular outcome occurring. It is expressed as a number between 0 (impossible event) and 1 (certain event), with numbers in between representing varying degrees of likelihood. In research, understanding probability helps researchers make informed decisions about sampling and understanding data.
Examples & Analogies
Think of throwing a coin. The probability of getting heads is 0.5, meaning there is a 50% chance of it landing on heads. In statistical research, researchers use similar concepts to predict and analyze the likelihood of certain characteristics within a population.
Questionnaire
Chapter 6 of 11
🔒 Unlock Audio Chapter

Chapter Content
A written list of questions to be asked in a survey or interview.
Detailed Explanation
A questionnaire is an essential tool in survey research, consisting of a set of structured questions designed to collect specific information from respondents. The way questions are phrased and the order they appear can affect the quality of responses, making careful design crucial for obtaining reliable data.
Examples & Analogies
Imagine planning a birthday party and asking friends for their preferences on food and activities. If you prepare a questionnaire to gather this information, you can ensure that you address everyone's likes and dislikes, just like researchers use questionnaires to capture detailed insights from their participants.
Randomisation
Chapter 7 of 11
🔒 Unlock Audio Chapter
Sign up and enroll to access the full audio experience
Chapter Content
Ensuring that an event (such as the selection of a particular item in the sample) depends purely on chance and nothing else.
Detailed Explanation
Randomisation is a crucial principle in sampling, where individuals or items are chosen in such a way that every member of the population has an equal chance of being selected. This helps eliminate biases and ensures that the sample accurately represents the broader population.
Examples & Analogies
Consider a lottery where winners are drawn from a pool of entries. Each ticket represents an equal chance of winning. This randomness ensures that the selection is fair and impartial, much like randomisation in survey sampling aims for fairness in selecting participants.
Reflexivity
Chapter 8 of 11
🔒 Unlock Audio Chapter
Sign up and enroll to access the full audio experience
Chapter Content
The researcher’s ability to observe and analyze oneself.
Detailed Explanation
Reflexivity refers to the process of self-examination by researchers regarding their biases, assumptions, and influences that might affect their research. A reflexive researcher critically reflects on their impact on the research process, the subjects studied, and how their perspectives might shape data interpretation.
Examples & Analogies
Think of a coach observing their team’s performance. A good coach will evaluate not just the players but also their coaching style, noting how their behavior influences the team dynamics. In research, reflexivity functions similarly, helping scholars consider their role in the study to provide more objective analysis.
Sample
Chapter 9 of 11

Chapter Content
A subset or selection (usually small) drawn from and representing a larger population.
Detailed Explanation
In research, a 'sample' is a smaller group selected from a larger population to be studied. The goal is to draw conclusions about the entire population based on the findings from this smaller group. A well-chosen sample can yield insights that are representative of the larger group.
Examples & Analogies
Imagine trying to guess the total number of apples in a large orchard. Instead of counting every single apple, you pick a few trees at random, count the apples there, and estimate the total based on that subset. This method reflects how sampling works in research.
Sampling Error
Chapter 10 of 11
🔒 Unlock Audio Chapter

Chapter Content
The unavoidable margin of error in the results of a survey because it is based on information from only a small sample rather than the entire population.
Detailed Explanation
Sampling error refers to the discrepancies that can occur when conclusions drawn from a sample do not perfectly reflect those from the entire population. This can occur simply because samples are uneven or unrepresentative, leading to variations between surveyed and non-surveyed groups.
Examples & Analogies
Think of trying to gauge the average height of high school students by measuring only a few randomly selected students from one class. If that class has unusually tall or short students, your measurements may not represent the average height of all students. This mismatched sample introduces sampling error.
Stratification
Chapter 11 of 11
🔒 Unlock Audio Chapter
Sign up and enroll to access the full audio experience
Chapter Content
According to the statistical sense, the subdivision of a population into distinct groups based on relevant criteria such as gender, location, religion, age etc.
Detailed Explanation
Stratification in statistics involves dividing a population into sub-groups (strata) based on specific characteristics, such as age, gender, or income level. This allows researchers to focus on different segments of the population in their analyses and can lead to more nuanced findings and tailored insights.
Examples & Analogies
Consider a fruit salad where you separate apples, oranges, and bananas into different bowls based on their type. By doing this, you can study how many of each fruit you have and understand their characteristics better. In research, stratifying a population helps achieve similar clarity on specific groups.
