3. Screen Scraping
Explanation:
1. The data analyze big data sets to gain insight, which a person can't do, so it is data mining.
2. A regression analysis shows the mathematical relationship between two variables. Association rule mining finds features of data points which determine the results of other features.

Answer:
It helps to give the geographic location of photos.
Explanation:
A geotag is added into the photography information when it's taken. That info is part of the EXIF information of a photo that lists a bunch of data related to the photo, like the camera brand, model, the aperture, the speed, the ISO, and so on.
That's assuming the GPS info is available of course, but if it's taken by a phone, it has the GPS info. Most mid-range and upper-range cameras have it too.
That information is used for example by Google Maps to present photos taken at a specific location.
Answer:
def average_strings(lst):
total_length = 0
avg = 0
for s in lst:
total_length += len(s)
avg = total_length/len(lst)
return avg
Explanation:
Create a function called average_strings that takes one parameter, lst
Initialize the total length and avg variables
Create a for loop that iterates through the lst. Get each string's length and put it to the total length
When the loop is done, calculate the average, divide total length by length of the lst
Return the average
