Sure, Insensitivity to sample size is a cognitive bias that refers to our tendency to rely heavily on a small amount of data, without considering the larger picture. This bias can lead us to draw incorrect conclusions or make inaccurate predictions, as we may not have enough information to make a well-informed decision. People often fall victim to this bias because our brains are wired to process information in a way that favors simplicity- and we often prefer to rely on easily accessible data, even if it is not representative of the larger population. Proper sample size is important to avoid this type of bias, as larger, more representative samples yield more accurate results.
Sure, here's a blog post about Insensitivity to sample size:
As conversion rate optimizers, we are always looking for ways to improve website performance and increase revenue. One aspect of optimization that often gets overlooked is sample size.
Insensitivity to sample size is a cognitive bias that occurs when people rely on small sample sizes to make conclusions about a larger population. This can lead to inaccurate conclusions and poor decision making.
Sample size refers to the number of individuals or data points that are included in a study or experiment. The larger the sample size, the more representative it is of the population it is trying to measure.
For example, if we are testing a new website design, we might only test it on 10 users. If all 10 users convert, we might assume that the new design is a success and roll it out to the entire user base. However, with such a small sample size, it's likely that the results aren't representative of the entire user base.
Sample size matters in optimization because we are trying to make decisions that impact the entire user base. If we make decisions based on a small, unrepresentative sample size, we risk making poor decisions that negatively impact user experience and revenue.
For example, let's say we are testing two different checkout flows. We test both on 10 users and find that the first checkout flow has a 50% conversion rate, while the second has a 60% conversion rate. Based on this sample size, we might conclude that the second checkout flow is the better option and roll it out to the entire user base. However, if we were to test both flows on a larger sample size, we might find that the difference in conversion rate is not statistically significant, and it's not worth implementing the second checkout flow.
To avoid insensitivity to sample size, it's important to use statistical analysis to determine whether or not a difference in conversion rate is statistically significant. This requires a larger sample size than simply relying on a small sample.
Additionally, it's important to ensure that any conclusions we draw from our optimization tests are based on statistically significant results. This means performing calculations to determine the level of confidence we have in our results, and making decisions accordingly.
Insensitivity to sample size is a cognitive bias that can lead to poor decision making in conversion rate optimization. It's important to use statistical analysis and larger sample sizes to avoid this bias, and to ensure that any decisions we make are based on statistically significant results. By avoiding insensitivity to sample size, we can make better decisions that positively impact user experience and revenue.
