As noted earlier, the normal deviate or Z score can be viewed as randomly sampled from the standard normal distribution.The chi-square distribution describes the probability distribution of the squared standardized normal deviates with degrees of freedom, df, equal to the number of samples taken.(The number of …
WebMar 28, 2024 · Hence, if the Chi-Square test statistic comes out to be greater than 18.475 then the results of the test would be considered statistically significant. Relation of alpha and chi-square statistic. Alpha and chi-square critical values are inversely proportional to each other. In other words, larger critical values lead to smaller alpha values.
WebMar 18, 2024 · R provides us the pchisq() function using which we can find the p-value of a Chi-Square Statistic. The syntax of this function is given below: Syntax: pchisq(q = “value”, df = “value”, lower.tail = TRUE) ... The probability in the right of q in the Chi-Square distribution is returned. Note that by default lower.tail is TRUE.
