Making predictions

Front

What does a strong positive relationship in a scatterplot indicate?

Back

A strong positive relationship indicates that as one variable increases, the other variable also increases significantly.

Front

What is the line of best fit in a scatterplot?

Back

The line of best fit is a straight line that best represents the data points in a scatterplot, showing the overall trend of the data.

Front

How can you determine the temperature if you know the number of customers in a shop?

Back

You can use the data from a scatterplot or a graph that correlates temperature with the number of customers to make predictions.

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data, showing how much one variable is affected by another.

Front

What does it mean if a scatterplot shows a weak relationship?

Back

A weak relationship means that there is little to no correlation between the two variables, and changes in one variable do not predict changes in the other.

Front

If the temperature is 60 degrees, how many customers are likely to come to the shop?

Back

Based on the data, if the temperature is 60 degrees, it is likely that a higher number of customers will come to the shop.

Front

What is the purpose of making predictions based on data?

Back

The purpose is to use existing data to forecast future outcomes or trends, helping in decision-making.

Front

How do you interpret a scatterplot with a negative relationship?

Back

A negative relationship indicates that as one variable increases, the other variable decreases.

Front

What is the significance of the slope of the line of best fit?

Back

The slope indicates the rate of change between the two variables; a steeper slope means a stronger relationship.

Front

What factors can affect customer turnout in a shop?

Back

Factors can include temperature, time of day, day of the week, and special promotions.
