Sample Size Determination
Determining the appropriate sample size for a survey based on the type of questions asked. Practice calculating sample size for questions that can be summarized with means or proportions. The sample size changes with the amount of variability in the population, the level of confidence, and the amount of allowable sampling error.

Visualizations Depend on Measurement Scale
good day. you are awwwwwwwsmmmm. but I finally found a video that I could leave comments, just so that I could contact you and ask a question. your economics graph, how to create supply and demand graph in excel. do you know how to do it with apple iMac? some of the techniques on Microsoft excel don't appear to be accessible in excel iMac. please advise. thank you. chris.
If using a Mac you follow the same procedure. Select scatterplot from the Insert tab. Then right click on the chart and choose Select Data. The menu screen looks different but has the same components (series list, x series, y series, and name). Empty the series list on the left (with - sign). Add each component just like in the video.
