conducting a and unbiased pieces of evidence to claim about the parameter. These will serve as your guide in computing for a sufficient number of respondents needed in your investigation about a certain topic of your interest and coming up with a reliable result. The scope of this module permits it to be used in many different learning situations. The language used recognizes the diverse vocabulary level of students. The lesson is arranged to follow the standard sequence of the course. In this module, you will compute for an appropriate sample size using the length of the interval. The module consists of only one lesson entitled Computing Appropriate Sample Size Using the Length of the Interval. After going through this module, you are expected to: 1. derive the formula for computing the appropriate sample size; and 2. compute for an appropriate sample size using the length of the interval. What I Know Let us see how far you will go and how much you know about this pretest. Please answer all questions with all your best and utmost honesty so that we can gauge your learning in the target competency of this lesson. If you obtain 100% or a perfect score, you may skip the module and immediately move to the next module. While in the event you missed a point, please proceed with the module as it will enrich your knowledge in computing for an appropriate sample size using the length of the interval. Let's get started!
