Sampling.<\/p>\n<p>Sampling is a data collection method that involves selecting a subset of individuals or elements from a larger population for study. This is done in order to save time and money, as it is often not feasible to study the entire population. The sample should be representative of the population, meaning that it should have the same characteristics as the population as a whole. This can be done by using random sampling, which ensures that each individual in the population has an equal chance of being selected.<\/p>\n<p>Observational studies are a type <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> of research that involves observing people or events without interfering with them. This type of study is often used to study human behavior, as it can be difficult to control all of the variables that might affect the results. Surveys are a type of research that involves asking people questions about their beliefs, attitudes, or behaviors. Surveys can be conducted in person, over the phone, or online. Experiments are a type of research that involves manipulating one variable and observing the effect that it has on another variable. Experiments are often used to test the effectiveness of new treatments or interventions.<\/p>\n<p>Here are some examples of sampling:<\/p>\n<ul>\n<li>A polling company might select a random sample of
