What Questions Should I Ask to Explore Univariate Distributions?

When exploring univariate data, it’s essential to understand the distributions and variability of the data.

Here are some good questions to ask when exploring distributions and variability in univariate data:

  1. What is the range of the data? This question helps you understand how spread out the data is. For example, “What is the range of temperatures in the dataset?”
  2. What is the average or mean of the data? This question helps you understand what the typical value is. For example, “What is the average age of people in the dataset?”
  3. What is the median of the data? This question helps you understand what the middle value is. For example, “What is the median income of people in the dataset?”
  4. What is the mode of the data? This question helps you understand which value appears most frequently. For example, “What is the mode of people’s favorite color in the dataset?”
  5. What is the variability in the data? This question helps you understand how much the data varies from the typical values. For example, “What is the standard deviation of test scores in the dataset?”
  6. What is the distribution of the data? This question helps you understand how the data is spread out across different values. For example, “Is the distribution of heights in the dataset normal or skewed?”
  7. Are there any outliers in the data? This question helps you identify any unusual or extreme values in the data. For example, “Is there a person in the dataset who is much older than everyone else?”
