What is correlation in a scatter plot?

Back

Correlation refers to the relationship between two variables in a scatter plot, indicating how one variable may change in relation to another.

Front

What are the types of correlation?

Back

1. Positive Correlation: As one variable increases, the other also increases. 2. Negative Correlation: As one variable increases, the other decreases. 3. No Correlation: No apparent relationship between the variables.

What does a scatter plot represent?

Back

A scatter plot represents the relationship between two quantitative variables, showing how they correlate with each other.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that is significantly different from other observations, often lying far outside the main cluster of points.

Front

How can you identify a positive correlation in a scatter plot?

Back

A positive correlation is identified when the points on the scatter plot slope upwards from left to right.

Front

How can you identify a negative correlation in a scatter plot?

Back

A negative correlation is identified when the points on the scatter plot slope downwards from left to right.

Front

What does it mean if there is no correlation in a scatter plot?

Back

No correlation means that there is no discernible pattern or relationship between the two variables being plotted.

Front

What is a trend line in a scatter plot?

Back

A trend line is a straight line that best represents the data points in a scatter plot, indicating the general direction of the data.

Front

How do you use a trend line to make predictions?

Back

To make predictions, extend the trend line and find the corresponding value on the other axis for a given input.

Front

What is the purpose of analyzing scatter plots?

Back

Analyzing scatter plots helps to understand relationships between variables, identify trends, and make predictions based on data.
