Critical Value Calculator

The calculator tool used to calculate the critical value of the given statistical values is called a Critical value calculator. The critical value is written as z- score or t-score for a given sample. Critical value is used to determine the boundaries and margin of error for a given sample.

Example 1: Calculate the critical value for the given alpha value = 0.02?

For the given alpha value first calculate (1- alpha value) = 1- 0.02 = 0.98

Now the next step is to calculate (1- alpha value)/ 2 = 0.98 / 2 = 0.49

So now z critical value is determined by looking into the z score table.

The corresponding value for 0.49 from the z score table is -2.0537.

Hence the critical value for alpha = 0.02 is -2.0537.

Example 2: Calculate the critical value for the given alpha value = 0.6?

For the given alpha value first calculate (1- alpha value) = 1- 0.6 = 0.4

Now the next step is to calculate (1- alpha value)/ 2 = 0.4 / 2 = 0.2

So now z critical value is determined by looking into the z score table.

The corresponding value for 0.2 from the z score table is 0.2533.

Hence the critical value for alpha = 0.6 is 0.2533.

I just want you to know how great Brinda has been in tutoring me on probability. She is patient and very knowledgeable in all concepts. I look forward to many more sessions with her. I appreciate her help and the great work that Tutor Pace is doing.

I have enjoyed my session with Aparna and it was helpful. I will hope to see her as my Math tutor in future sessions as well.

Your tutor has been such an inspiration to me as I have difficulty getting some of the physics concepts down and truly understanding them. She takes the time to fully explain each and every aspect of any problem I might ask for help and always with encouragement and humor.
