Is there a causal relationship between the time of sunrise and the daily high temperature?

Casual Relationship: if change in one quantity causes change in a second quantity, then the quantities have a causal relationship.

Correlation does not necessarily mean causation.

Just think of Arctic Circle, where the sun is up 24 hours a day during the summer.

To determine if there is a causal relationship between the time of sunrise and the daily high temperature, we need to collect and analyze data. Here are the steps you can follow to investigate this question:

1. Gather data: Obtain data on the time of sunrise and the daily high temperature for a significant number of days across different seasons and locations. You can access this information from meteorological databases, weather websites, or local weather stations.

2. Organize the data: Create a spreadsheet or table to organize the data. Each row should represent a specific day, while columns can include variables such as date, time of sunrise, and daily high temperature.

3. Analyze the data: Plot the data points on a scatter plot, with time of sunrise on the x-axis and daily high temperature on the y-axis. Look for any noticeable trends or patterns in the data.

4. Statistical analysis: Perform a statistical analysis to determine the strength and significance of any relationship between the time of sunrise and the daily high temperature. Common statistical techniques include correlation analysis or regression analysis. Correlation coefficients can indicate the strength and direction of the relationship, while regression models can help predict the daily high temperature based on the time of sunrise.

5. Consider confounding factors: Take into account any other variables that may have an influence on daily high temperature, such as weather conditions, geographical location, or seasonal changes. It's important to control for these factors to isolate the potential causal relationship between time of sunrise and daily high temperature.

6. Interpret the results: Based on the analysis, you can determine if a causal relationship exists between the time of sunrise and the daily high temperature. If the statistical analysis suggests a strong and significant relationship, it may indicate that the time of sunrise causally influences the daily high temperature. However, if the relationship is weak or non-existent, it suggests that other factors play a more significant role in determining the daily high temperature.

Remember that correlation does not imply causation. While a strong correlation may suggest a causal relationship, further studies and experiments may be required to establish a definitive cause-and-effect connection between the time of sunrise and the daily high temperature.
