Question

data values were gathered from residents of several small towns in the united states. students in kindergarten class dot plot with numbers 9,10,11,12,13,14,15,16,17,18,19,20,21,22 on the horizontal axis, dots above each number what type of data values are represented? options: univariate categorical, bivariate categorical, univariate numerical, bivariate numerical

Explanation:

1. First, understand the definitions:

• Univariate data involves one variable. Numerical data consists of numbers (like ages, heights, counts). Categorical data consists of groups or categories (like colors, genders).
• Bivariate data involves two variables.

1. The dot - plot here shows the number of students (a numerical value) for different age groups (the variable is the age, and we are looking at the number of students for each age). Since we are dealing with one variable (the age - related count of students) and the data is numerical (the number of students), it is univariate numerical data.

• Univariate categorical would be if we had categories (like types of pets) with counts, but here the data on the x - axis (10, 11, 12, …, 21) are numerical values representing ages (or some numerical measure) and we are counting the number of students (a numerical quantity) for each of these values. Bivariate data would involve two variables (e.g., age and height of students), which is not the case here.

Answer:

Univariate numerical
