How can, At the core of biology and other sciences lies a problem-solving approach called the scientific method. In order to formulate a good hypothesis, it is important to think about different questions you might have about a particular topic. However, there is a generally accepted sequence of steps in scientific methods. Instead, it's a possible explanation that we can test to see if it is likely correct, or if we need to make a new hypothesis.

It just means there is a possible logical explanation. For example, human intelligence may be operationally defined as what an intelligence test measures, Repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding can be reproduced, A descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles, A descriptive technique for obtaining the self-reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group, A flawed sampling process that produces an unrepresentative sample, All those in a group being studied, from which samples may be drawn, A sample that fairly represents a population because each member has an equal chance of inclusion.

Unless there was a flaw in the testa possibility we should always considera contradictory result means that we can discard the hypothesis and look for a new one. Descriptive research methods can be crucial for psychological researchers to establish and describe the natural details of a particular phenomenon.
