Methods Used to Collect Data
{"Image DocumentName": "Methods Used to Collect Data", "Image ImageDescription": "Systematic Sample: A sample in which every kth item of the sampling frame is selected, starting from the first element which is randomly selected from the first k elements. Note: The systematic technique is easy to execute. However, it has some inherent dangers when the sampling frame is repetitive or cyclical in nature. In these situations the results may not approximate a simple random sample. Stratified Random Sample: A sample obtained by stratifying the sampling frame and then selecting a fixed number of items from each of the strata by means of a simple random sampling technique.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
