Is forming a hypothesis is the same as solving a problem?
No To form a hypothesis is an attempt to explain something just by your own thought (could be anything, but typically an observation, phenomenon, or some other scientific problem). To be a "valid hypothesis" the hypothesis should be testable (typically through empiric investigation) ... and it probably shouldn't sound outright absurd (from a scientific POW) ... depends. ... hope that helps.

How to conduct Mann-Kendall test for trend analysis?
by using this formula where y=data values at times i and j and n=length of the data set and Under the null hypothesis that yi are independent and randomly ordered, the statistic S is approximately normally distributed when n≥8, with zero mean and variance as follows: The standardized test statistic ZS is computed by: Decide on a probability level of significance (95% typically) The trend is said to be decreasing if ZS is negative and the computed probability is greater than the level of significance. The trend is said to be increasing if the ZS is positive and the computed probability is greater than the level of significance. If the computed probability is less than the level of significance, there is no trend. you can use Excel to compute the equations. Tq
What is the relationship between levels of confidence and statistical significance?
The connotation 'statistical significance' takes into account the number of samples as well level of confidence in making a conclusion based on these samples. The level of confidence is typically denoted as 1-alpha (1 minus alpha), where alpha is basically the chance that the reported conclusion will incorrect. The most popular level of confidence is 95%, which coincides with a 5% alpha, meaning that when one makes a conclusion based on a particular sample, there is a 5% chance of a false or incorrect conclusion.

Forming a hypothesis - to explain the observation.
What is a statement of no difference in experimental treatments?
When setting up an experimental procedure one prepares a control treatment as well as one or more experimental treatments. At the end of the experiment, if there is no difference between the experimental and control groups the experiment is typically said to be not conclusive. With a typical set-up, this result generally fails to lead to a rejection of the null hypothesis.
How long does a cystoscopy take?
the procedure typically takes 10-40 minutes to complete.
What is a forest fortnight?

What is each sample does not necessarily have the same properties as every other sample?
You will typically have an experimental parameter that will be varied as part of testing a hypothesis.
Is it rare to prove a hypothesis through experimentation true or false?
It is rare and difficult to prove a hypothesis true or false through experimentation. While it is typically easy to prove something completely false, proving it true is another story.

Do you already know the correct answer to a hypothesis before you being collecting data?
Typically, no. While a researcher might anticipate a particular result, the hypothesis is only that - what the expected result might be (and often, there may be several possible expected results or even none.)
Does blue cross cover dermotology visits?
