EXPERIMENTAL METHOD ⮚ Defines the cause-and-effect relationships of a certain parameter or event under a controlled condition. 5. TEST METHOD ⮚ Widely used in psychological research and psychiatry. Standard Tests are used because of their validity, reliability, and usability. 6. MECHANICAL DEVICES ❖ Social/ Educational Research ⮚ Camera, projector, videotape, tape recorder ❖ Chemical/ Biological/ Medical Research ⮚ X- ray machine, microscope, ultrasound, weighing scales, CT scans ❖ Astronomy/ Atmospheric Research

Bar Graph (Horizontal, Vertical, One Hundred Percent Bar) ⮚ Are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger. www.splashlearn.com c. Pictograph ⮚ is a symbol or image that represents an idea www.jr.brainpop.com d. Pie Chart ⮚ is a special chart that uses pie slices to show relative sizes of data. www.originlab.com e. Statistical Maps ⮚ A special type of map in which the variation in quantity of a factor such as rainfall, population, or crops in a geographic area is indicated; a dot map is one type.

Scatter Diagrams ⮚ is a type of data visualization that shows the relationship between different variables. This data is shown by placing various data points between an x- and y-axis. https://www.spforexcel.com POPULATIONS & SAMPLES ● POPULATION ⮚ The complete collection of elements to be studied. ⮚ Can be classified either finite or infinite. ● SAMPLE ⮚ A sub- collection of elements drawn from a population. ⮚ Can be either a purposive or a probability sample. Example: A manufacturer of kerosene heaters wants to determine if customers are satisfied with the performance of their heaters. Toward this goal, 5 000 of his 200 000 customers are contacted and each is asked, “Are you satisfied with the performance of the kerosene heater you purchased?” POPULATION: 200 000 customers SAMPLE: 5 000 customers SAMPLING TECHNIQUES
1. PROBABILITY SAMPLING ⮚ Also called the Simple Random Sampling.
