## Is 0.2 A strong correlation?

There is no rule for determining what size of correlation is considered strong, moderate or weak. For this kind of data, we generally consider correlations above 0.4 to be relatively strong; correlations between 0.2 and 0.4 are moderate, and those below 0.2 are considered weak.

## Can P-value ever be 0?

In theory, it’s possible to get a p-value of precisely zero in any statistical test, if the observation is simply impossible under the null hypothesis. In practice, this is extremely rare.

## What does a correlation of 0.01 mean?

The tables (or Excel) will tell you, for example, that if there are 100 pairs of data whose correlation coefficient is 0.254, then the p-value is 0.01. This means that there is a 1 in 100 chance that we would have seen these observations if the variables were unrelated.

## What is the decision rule for Chi Square?

Chi square value is NEVER negative. For df = 1 and alpha = . 05, the critical value is 3.84. So the decision rule is to reject ho if the Chi-Square test statistic is greater than 3.84, otherwise do not reject ho.

## How do I report chi square results in SPSS?

Quick Steps

- Click on Analyze -> Descriptive Statistics -> Crosstabs.
- Drag and drop (at least) one variable into the Row(s) box, and (at least) one into the Column(s) box.
- Click on Statistics, and select Chi-square.
- Press Continue, and then OK to do the chi square test.

## Is P value 0.04 Significant?

The Chi-square test that you apply yields a P value of 0.04, a value that is less than 0.05. The interpretation is wrong because a P value, even one that is statistically significant, does not determine truth.

## What does P-value in chi-square mean?

P-value. The P-value is the probability of observing a sample statistic as extreme as the test statistic. Since the test statistic is a chi-square, use the Chi-Square Distribution Calculator to assess the probability associated with the test statistic.

## How do you use a chi-square distribution table?

In summary, here are the steps you should use in using the chi-square table to find a chi-square value:

- Find the row that corresponds to the relevant degrees of freedom, .
- Find the column headed by the probability of interest…
- Determine the chi-square value where the row and the probability column intersect.

## How do you report chi square results?

Chi Square Chi-Square statistics are reported with degrees of freedom and sample size in parentheses, the Pearson chi-square value (rounded to two decimal places), and the significance level: The percentage of participants that were married did not differ by gender, X2(1, N = 90) = 0.89, p > . 05.

## What does P-value of 0.01 mean?

P < 0.01 ** P < 0.001. Most authors refer to statistically significant as P < 0.05 and statistically highly significant as P < 0.001 (less than one in a thousand chance of being wrong).
