Scatterplots and Two Way Tables CHECK

Front

What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional grid.

Front

What does a positive linear association in a scatterplot indicate?

Back

A positive linear association indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative linear association in a scatterplot indicate?

Back

A negative linear association indicates that as one variable increases, the other variable tends to decrease.

Front

What does 'no association' mean in the context of scatterplots?

Back

'No association' means that there is no discernible relationship between the two variables being plotted.

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that is significantly different from other observations, often lying far away from the trend of the data.

Front

How do you determine the coordinates of an outlier in a scatterplot?

Back

The coordinates of an outlier are determined by identifying the point that does not fit the overall pattern of the data.

Front

What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of two categorical variables.

Front

How can you interpret data from a two-way table?

Back

Data from a two-way table can be interpreted by analyzing the relationships and frequencies between the two categorical variables.

Front

What does it mean if a two-way table shows more members in one category than another?

Back

It indicates a higher frequency or occurrence of that category compared to the other.

Front

What is the purpose of surveying in statistics?

Back

The purpose of surveying is to collect data from a sample to make inferences about a larger population.
