**[Statistics] When to use the z-test versus t-test a flowchart**

In comparing pie charts and bar graphs, it is generally agreed that between these two kinds of graphs, bar graphs are superior. One reason for this is that it is much easier for the human eye to tell the difference between the heights of bars than wedges in a pie. If there are several categories to graph, then there can be a multitude of pie wedges that appear to be identical. With a bar graph... A bar chart is the most common type of diagram, and is frequently used. . It represents data in terms of bars of equal width, whose height varies to represent the size of the data.

Donâ€™t use a pie chart if the category values are almost identical or completely different. You could add labels, but thatâ€™s a patch, not an improvement. You could â€¦... T-charts are great organizational tools to help solve equations with more than one variable. Whenever you have equations with unknowns, you can use a T-chart to organize and solve a problem.

The T Statistic is used in a T test when you are deciding if you should support or reject the null hypothesis. Itâ€™s very similar to a Z-score and you use it in the same way: find a cut off point, find your t score, and compare the two.... Excel doesnâ€™t provide a step chart capability, but we can create one by using the scatter chart capability shown above. Example 4 : Create a step chart for the data in Figure 7.

- In real life we usually don't, but statistics courses like to contrive problems where we do. Whether or not the population is normally distributed. This is mainly important when dealing with small sample sizes. The size of our sample. The magic number is usually 30 - below that is considered a "small" sample, and 30 or above is considered "large". When the sample size is large, the central
- 11/06/2018Â Â· The vertical line of a T chart should be the longest line of the T chart. Use your ruler to measure the width of the page and find the middle. Place your ruler vertically in the center of the page and draw a line from the top to the bottom of the page. If you would like a margin around your T chart simply erase parts of the top and bottom of the line until youâ€™ve reached your desired margin.

- Compute the t-statistic for the null hypothesis using the equation: Every t-test has associated with it a value of degrees of freedom (df). (This is related to the discussion of the appropriate multiplier to use in the computation of the confidence interval as discussed above.)
