    How Do Researchers Come up With a Hypothesis?

    In many cases, researchers might draw a hypothesis from a specific theory or build on previous research. For example, prior research has shown that stress can impact the immune system. So a researcher might for a specific hypothesis that: "People with high-stress levels will be more likely to contract a common cold after being exposed to the virus than are people who have low-stress levels."

    In other instances, researchers might look at commonly held beliefs or folk wisdom. "Birds of a feather flock together" is one example of folk wisdom that a psychologist might try to investigate. The researcher might pose a specific hypothesis that "People tend to select romantic partners who are similar to them in interests and educational level."

    Elements of a Good Hypothesis

    When trying to come up with a good hypothesis for your own research or experiments, ask yourself the following questions:

    Is your hypothesis based on your research on a topic?

    Can your hypothesis be tested?

    Does your hypothesis include independent and dependent variables?

    Before you come up with a specific hypothesis, spend some time doing background research on your topic. Once you have completed a literature review, start thinking about potential questions you still have. Pay attention to the discussion section in the journal articles you read. Many authors will suggest questions that still need to be explored.

    How to Form a Hypothesis

    The first step of a psychological investigation is to identify an area of interest and develop a hypothesis that can then be tested. While a hypothesis is often described as a hunch or a guess, it is actually much more specific. A hypothesis can be defined as an educated guess about the relationship between two or more variables.

    For example, a researcher might be interested in the relationship between study habits and test anxiety.

    The researcher would propose a hypothesis about how these two variables are related, such as "Test anxiety decreases as a result of effective study habits."

    In order to form a hypothesis, you should take these steps:

    Start by collecting as many observations about something as you can.

    Evaluate these observations and look for possible causes of the problem.

    Create a list of possible explanations that you might want to explore.

    After you have developed some possible hypotheses, it is important to think of ways that you could confirm or disprove each hypothesis through experimentation. This is known as falsifiability.

  3. The total time the water balloon is in the air is 8 seconds. The balloon reaches the maximum height of 25 fee after 3 seconds. The water balloon has a height of 24 feet at 2 seconds and a half.

  4. x =-.20752

    step-by-step explanation:

    4^(x+2)=12

    4^(x+2)=12

    take the log base 4 on each side

    log 4 (4^(x+2) = log 4(12)

    we know log b(a^y) = y log b (a)

    (x+2) log 4(4) = log 4 (12)

    x+2 = log 4 (12)

    we know   logb c = loga c/loga b

    we want to convert to base 10   so a = 10

    by default, we do not write the 10   c = 4   and b = 10

    log4 10 = log 12/log 4

    log4 10 = log 12/ log 4

    x+2 = log 12/ log 4

    subtract 2 from each side

    x +2 -2 = log 12/ log 4 -2

    x = 1.79248125 -2

    x =-.20752
