Question

high school students were surveyed, and the data collected are shown. what type of data is represented? chart: time practicing piano (vertical label), minutes (horizontal axis) with a box - plot options: univariate categorical, bivariate categorical, univariate numerical, bivariate numerical

Explanation:

1. First, recall the definitions:

• Univariate data involves one variable.
• Bivariate data involves two variables.
• Categorical data is non - numerical (like labels, groups), while numerical data is quantitative (numbers with meaning like time, height, etc.).

1. The box - plot here represents the "Time Practicing Piano" (in minutes). So we are dealing with one variable (time) which is numerical.

• It is not bivariate because there is only one variable (we are not looking at the relationship between two variables).
• It is not categorical because time in minutes is a numerical value (we can perform arithmetic operations on it, like finding the average time). So it is univariate numerical data.

Answer:

Univariate numerical
