TEKS 7.6H Qualitative and Quantitative Predictions

Front

What is a qualitative prediction?

Back

A qualitative prediction is a forecast based on observations and descriptions rather than numerical data. It focuses on qualities or characteristics.

Front

What is a quantitative prediction?

Back

A quantitative prediction is a forecast that involves numerical data and measurements. It focuses on quantities and can be expressed with numbers.

Front

How do you determine if an event is 'more likely than' another?

Back

An event is 'more likely than' another if it has a higher probability of occurring based on available data or evidence.

Front

How do you determine if an event is 'less likely than' another?

Back

An event is 'less likely than' another if it has a lower probability of occurring based on available data or evidence.

Front

What is the importance of making predictions in science?

Back

Making predictions helps scientists test hypotheses, understand relationships between variables, and anticipate outcomes of experiments.

Front

Give an example of a qualitative prediction.

Back

An example of a qualitative prediction is saying that it will be a sunny day based on observing clear skies.

Front

Give an example of a quantitative prediction.

Back

An example of a quantitative prediction is forecasting that the temperature will rise to 75 degrees Fahrenheit tomorrow.

Front

What role do observations play in qualitative predictions?

Back

Observations provide the basis for qualitative predictions by allowing individuals to assess conditions and make informed forecasts.

Front

What role do measurements play in quantitative predictions?

Back

Measurements provide the numerical data needed for quantitative predictions, allowing for precise forecasts based on statistical analysis.

Front

What is the difference between a hypothesis and a prediction?

Back

A hypothesis is a testable statement about the relationship between variables, while a prediction is a specific forecast about what will happen in an experiment.
