This video will show you how to find a confidence interval for variance and standard deviation using the Chi-Square chart and the TI-84. I use 2 examples to cearly explain how to find the confidence interval for variance and standard deviation.

Subscribed!!!! Love your energy! In the future, could you do a video on finding the confidence interval for a population correlation coefficient (p)?

Is it possible to find the values of the chi-square distribution chart from our calculator or do we always need access to a chart from a textbook or website somewhere?

At the 5:05 mark you said x2 was 26.296, but you wrote 29.296. Just wanted to let you know

The music is a bit loud... hard to hear your voice at times.
