Here is the instruction:
Use the data from the table to calculate the number of hours of daylight for one day per week throughout the year (52 data points). Be sure to use the same day of the week so that your data points are evenly spaced 7 days apart.
Does this mean...
Jan. 1
Jan. 7
Jan. 14
Jan.21
Jan.28
Etc..
Or
Jan.1
Jan. 8
Jan.15
Jan.22
Jan.29
Etc..
Well, my friend, I must clownfess that the first option you mentioned is the correct one! So, it would go like Jan. 1, Jan. 8, Jan. 15, Jan. 22, Jan. 29, and so on. Remember, we want those data points to be evenly spaced 7 days apart, just like the number of calories in a clown's diet. It's all about balance, you know!
Based on the instruction provided, you should use the same day of the week and evenly space your data points 7 days apart.
Therefore, the correct sequence would be:
Jan. 1, Jan. 8, Jan. 15, Jan. 22, Jan. 29, and so on.
To calculate the number of hours of daylight for one day per week throughout the year, you need to use the same day of the week and have evenly spaced data points that are 7 days apart.
In the first scenario you mentioned:
Jan. 1
Jan. 7
Jan. 14
Jan. 21
Jan. 28
You are starting on Jan. 1 and then adding 7 days to get the subsequent dates. This would give you the same day of the week (e.g., Monday) but the data points are not evenly spaced 7 days apart. For example, there are only 6 days between Jan. 1 and Jan. 7, and 13 days between Jan. 7 and Jan. 14.
In the second scenario you mentioned:
Jan. 1
Jan. 8
Jan. 15
Jan. 22
Jan. 29
You are starting on Jan. 1 and then adding 7 days to get the subsequent dates. This follows the requirement of using the same day of the week and having evenly spaced data points that are 7 days apart. For example, there are exactly 7 days between Jan. 1 and Jan. 8, and between Jan. 8 and Jan. 15.
Therefore, the second scenario is the correct approach for calculating the number of hours of daylight for one day per week throughout the year.
