So, we have to look at -2.0 in the z column and the value in the 0.09 column. We have to look at the value of 2.09 in the Z table. We will have to find the sample proportion Use the following data for the calculation of P-Value. Find out the approximate P-Value for the researcher’s test if we were to assume that the necessary conditions are met, and the significance level is 5%. He finds that 80 out of 240 people sampled can speak Hindi. He commissions a survey in his village to find out the number of people who can speak Hindi. Here, p is the proportion of people in the village who speak Hindi. Hence, the frames the null and alternative hypotheses. A researcher is curious if the figure is higher in his village. Example #2Ģ7% of people in India speak Hindi, as per a research study. The P-value, greater than the significance level, indicates that we fail to reject the null hypothesis.Ī) Since the p-value of 0.3015 is greater than the level of significance of 0.05 (5%), we fail to reject the null hypothesis.ī) Since the p-value of 0.0129 is less than the level of significance of 0.05, we reject the null hypothesis. A very small P-value, which is lesser than the significance level, indicates that you reject the null hypothesis. The significance level (α) is a predefined threshold the researcher sets. In addition, tables, spreadsheet programs, and statistical software help calculate the P-value. P-value in excel P-value In Excel P-value is used in correlation and regression analysis in Excel to determine whether the result obtained is feasible or not and which data set from the result to work with. An alternative hypothesis is the one you would believe if the null hypothesis is untrue. read more is a default position that there is no relationship between two measured phenomena. So, even if a sample is taken from the population, the result received from the study of the sample will come the same as the assumption. The null hypothesis Null Hypothesis Null hypothesis presumes that the sampled data and the population data have no difference or in simple words, it presumes that the claim made by the person on the data or population is the absolute truth and is always right. In addition, it helps determine the significance of the results. P is a statistical measure that helps researchers to determine whether their hypothesis is correct.
