3. Using Tables to Find Areas and Percentiles

I work through some examples of finding areas under the standard normal curve using the standard normal table. If you fully understand how to find values in the standard normal table, this video will not be of much use to you. The table used is one that gives areas to the left of z (the … Read more

I work through some examples of finding the z value corresponding to a given area under the standard normal curve, using the standard normal table. If you fully understand how to find values in the standard normal table, this video will not be of much use to you. The table used is one that gives … Read more

I work through some examples of finding areas under the standard normal curve using the standard normal table. If you fully understand how to find values in the standard normal table, this video will not be of much use to you. The table used is one that gives areas between 0 and z.

I show how to find percentiles and areas for the F distribution using the F table. In the first part of the video I work through examples finding areas and percentiles in the right tail of the distribution. (These are often of more importance to us than the left tail values.) In the second part … Read more

I show how to find percentiles and areas for the F distribution using R (a free statistical software package), using the commands qf and pf.

I show how to find percentiles and areas for the chi-square distribution using the chi-square table.

I show how to find percentiles and areas for the chi-square distribution using R (a free statistical software package), using the commands qchisq and pchisq.
