Correlation and Causation in Praxis Core Math

What is the main topic of the problem discussed in the video?

• The correlation between frostbite cases and sledding accidents

• The relationship between temperature and hospital visits

• The causes of hospital admissions in winter

• The impact of weather on outdoor activities

What does a positive correlation between two variables indicate?

• One variable causes the other

• As one variable increases, the other also increases

• There is no relationship between the variables

• As one variable increases, the other decreases

In the scatterplot example, what does a dot represent?

• A single accident

• A single patient

• A single day

• A single hospital

Why is it important to be cautious about assuming causality from correlation?

• Because correlation always implies causation

• Because there might be other underlying factors

• Because data collection methods are always flawed

• Because it is impossible to determine causality

What underlying factor is suggested as a possible cause for both frostbite cases and sledding accidents?

• Snowfall

• Wind speed

• Temperature

• Humidity

Which choice suggests that frostbite directly causes sledding accidents?

• Both the number of frostbite cases and the number of sledding accidents are negatively correlated with temperature

• The hospital treats more sledding accidents than frostbites

• The frostbite cases and sledding accidents were not randomly selected

• People with frostbites tend to have more difficulty controlling sleds

What does the choice about data collection methods imply?

• Temperature is the main factor

• The data might not be reliable

• Sledding accidents cause frostbite

• Frostbite causes sledding accidents

Which choice directly addresses the main issue of correlation not implying causation?

• The hospital treats more sledding accidents than frostbites

• Both the number of frostbite cases and the number of sledding accidents are negatively correlated with temperature

• The frostbite cases and sledding accidents were not randomly selected

• People with frostbites tend to have more difficulty controlling sleds

What is the final choice selected in the video?

• People with frostbites tend to have more difficulty controlling sleds

• The hospital treats more sledding accidents than frostbites

• Both the number of frostbite cases and the number of sledding accidents are negatively correlated with temperature

• The frostbite cases and sledding accidents were not randomly selected

What is the main takeaway from the video regarding correlation and causation?

• Correlation always implies causation

• Correlation and causation are the same

• Correlation does not necessarily imply causation

• Causation can be easily determined from correlation
