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.

What is Mann Kendall test and how to perform it for trend analysis of rainfall and runoff?
Mann-Kendall test
An analysis of variance differs from a t test for independent means in that an analysis of variance?
Analysis of Variance (ANOVA) compares 3 or more means. The t-test would only compare 2 means.
Where do scientists test their hypothesis?
In a lab or wherever they can conduct an experiment
How can correlation and regression analysis be used to make strategic decisions in a dynamic competitive business environment filled with risk and uncertainty.?
Correlation and regression analysis can help business to investigate the determinants of key variables such as their sales. Variations in a companies sales are likely to be related to variation in product prices,consumers,incomes,tastes and preference's multiple regression analysis can be used to investigate the nature of this relationship and correlation analysis can be used to test the goodness of fit. Regression can also be used to estimate the trend in a time series to make forecast

How do you test to see if its nickel?
You can test if a material is nickel by using a nickel spot test kit or by performing a nickel chloride test. Another method is to conduct an X-ray fluorescence (XRF) analysis of the material to determine its elemental composition.
How do you test a filtrate without using water?
To test a filtrate without using water, you can conduct qualitative analysis tests such as flame tests, chemical reagents tests, or spectroscopic analysis. These tests can provide information about the composition of the filtrate without the need for additional water.
