Exploring Scatter Plots and Bivariate Data

What does 'bivariate' mean in the context of data?

• Data that varies twice as much

• Data collected over two years

• Data with binary values

• Data with two variables

Which of the following is an example of bivariate data?

• Favorite genres of music

• Color preferences among individuals

• Population of a city

• Temperature over time

How can bivariate data be displayed apart from scatter plots?

• Input-output tables

• Histograms

• Frequency polygons

• Stem-and-leaf plots

How is bivariate data best represented?

• Using a line chart

• Through a bar graph

• On a scatter plot

• In a pie chart

What is the purpose of plotting bivariate data on a graph?

• To identify the mode of the dataset

• To determine the median value of the dataset

• To calculate the mean of the variables

• To visualize the relationship between two variables

What does a scatter plot illustrate about bivariate data?

• The difference between two sets of data

• The average value of the data set

• The correlation between two variables

• The total sum of all data points

What does a scatter plot with no clear pattern suggest?

• A strong correlation

• No correlation

• Only positive correlation

• Only negative correlation

What is an outlier in the context of scatter plots?

• The lowest value in the data set

• The most common data point

• A data point that does not fit the general trend

• The highest value in the data set

What signifies a positive correlation in a scatter plot?

• Data points are close to each other

• As one variable increases, the other also increases

• Data points form a downward trend

• As one variable increases, the other decreases

Which variables could have a positive correlation?

• Number of hours studied and test scores

• Temperature and layers of clothing worn

• Height of a tree and depth of its roots

• Amount of rain and number of sunglasses sold
