- [Speaker] The last topic I'm going to cover with respect to conversion rates, is setting time frames for calculating the rates. In earlier videos, I showed you some data I made up about conversion frequencies. You know, the numerator of a conversion rate. Remember these charts of those data where I graphed the conversions aggregated by day, and compared them to how it looks when I graph the same conversions aggregated by week? I pretended these conversions came from online app sales. So when we look at the data as a daily graph, it's all jagged because some of the days we don't sell any apps at all and some days, we sell as many as five.
