E. Increasing
is that correct
Yes, that is correct. The data can be described as having a positive trend, indicating that as the student's age increases, the number of times they cry each month on average also increases. The data also has a linear trend, meaning that the relationship between age and crying frequency can be approximated by a straight line. Additionally, the data shows an increasing pattern, with the number of cries per month generally increasing as the student's age increases.
To determine which vocabulary words can be used to describe the data represented in the scatterplot, we need to understand the relationship between the variables on the x-axis and y-axis.
A. Decreasing: This word means that as the value on the x-axis increases, the value on the y-axis decreases. We cannot determine if this is true based on the given information, so it cannot be used to describe the data.
B. Proportional: This word means that there is a constant ratio between the values on the x-axis and y-axis. We cannot determine if this is true based on the given information, so it cannot be used to describe the data.
C. Positive trend: This word means that as the value on the x-axis increases, the value on the y-axis also increases. We cannot determine if this is true based on the given information, so it cannot be used to describe the data.
D. Linear trend: This word means that the data points on the scatterplot form a straight line. We cannot determine if this is true based on the given information, so it cannot be used to describe the data.
E. Increasing: This word means that as the value on the x-axis increases, the value on the y-axis increases. We cannot determine if this is true based on the given information, so it cannot be used to describe the data.
F. Bivariate: This word means that there are two variables being considered in the scatterplot - the x-axis variable (age) and the y-axis variable (number of times cried). This is true based on the given information, so it can be used to describe the data.
G. Univariate: This word means that there is only one variable being considered in the scatterplot. Since there are two variables (age and number of times cried) represented on the axes, this word cannot be used to describe the data.
Based on the given information, the vocabulary words that can be used to describe the data represented in the scatterplot are:
- F. Bivariate
