Example Dataset
An example of the data we might have collected in the previous video is shown here:

Date	Day of Week	Time Spent On Site (X)	Buy (Y)
June 15	Thursday	5	No
June 15	Thursday	10	Yes
June 16	Friday	20	Yes
Question 1 of 2
What type of variable is the random variable X in the video in the previous concept?

In the provided dataset:

- **Date**: June 15, June 16
- **Day of Week**: Thursday, Friday
- **Time Spent On Site (X)**: 5, 10, 20 (measured in minutes)
- **Buy (Y)**: No, Yes

### Understanding the random variable X:

The variable **X** represents "Time Spent on Site." It takes numerical values like 5, 10, and 20 minutes, which means it is a **quantitative variable**. Since these values can vary in a continuous manner and measure time, **X** is specifically a **continuous random variable**. 

### Characteristics of X:
- **Quantitative**: It represents a measurable quantity (time).
- **Continuous**: Time can be measured in increasingly small intervals (e.g., 5.1 minutes, 10.2 minutes, etc.).

Thus, **X** (Time Spent on Site) is a **continuous quantitative random variable**.
