Statistics - Z table - The following table shows the area under the curve to the left of a z-score:
然后Table 3.1 给出了这些量之间的correlations, Table 3.2 给出了每个量的 coefficient 和 standard error,以及他们的商也就是 Z-score(Z core 为 2 差不多对应 p=0.05 的置信度)。除了算 Z-score 还可以用 F-statistic 来算置信度。 3.2.2 The Gauss-Markov Theorem 在所有的线性无偏估计中,如果误差满...
The z-table is divided into two sections, negative and positive z-scores. Negative z-scores are below the mean, while positive z-scores are above the mean. Row and column headers define the z-score while table cells represent the area. Learn how to use this z-score table to find probab...
You can use your knowledge of normal distributions (like the 68 95 and 99.7 rule) or the z-table to determine what percentage of the population will fall below or above your result. The z-score is calculated using the formula: z = (X-μ)/σ Where: σ is the population standard ...
If Tom looked up his Z-score on a table of standard normal probabilities, he would find it associated with the number 0.7486. This tells him that he did better than 75 percent of the people who took the test and that 25 percent of the students outperformed him. ...

The probability of an observation having a z-score between 0.40 and 0.65 is 8.675%. Using only simple math and a z-table, you can easily find the probabilities that you need! Alternatively,use the Empirical Ruleto find probabilities for values in a normal distribution using ranges based on ...
Here we have 0.025 in each tail. Looking up 1 - 0.025 in our z-table, we find a critical value of 1.96. Thus, our decision rule for this two-tailed test is: If Z is less than -1.96, or greater than 1.96, reject the null hypothesis.Calculate Test Statistic: ...
Cross tabulation(also known as contingency table) is a table to reveal the frequency distribution of the variables. Analysis based on the table can determine whether there is a significant relationship, obtain the strength and direction of the relationship, and measure and test the agreement of mat...
