SQL Date and time Function

The HH is the hour of the day, from 0 to 23.

The MM is the minute of the hour, from 0 to 59.

The SS is the seconds within a minute, from 0 to 59.

This returns the seconds, SS, of the timestamp column!

For strftime(__, timestamp):

  • %Y returns the year (YYYY)
  • %m returns the month (01-12)
  • %d returns the day of the month (1-31)
  • %H returns 24-hour clock (00-23)
  • %M returns the minute (00-59)
  • %S returns the seconds (00-59)

if sign_up_at format is YYYY-MM-DD HH:MM:SS.

Binomial Test in Python

  Binomial Test Let’s imagine that we are analyzing the percentage of customers who make a purchase after visiting a website. 1000 customers visited the site this month, and 58 of them made a purchase. The marketing department reports that historical data suggests about 72 of every 1000 visitors make a purchase. Thus, they estimate that the probability of any particular customer making a purchase is 7.2%. We would like to know if this month’s number, 58 purchases, is significantly different from normal or a reasonable fluctuation due to random chance. In previous exercises, we collected samples of numerical information (eg. order price) and then used the mean and standard deviation of those samples to make comparisons. In contrast, we now have a sample where each unit (a visitor) falls into one of two discrete categories: “made a purchase” “did not make a purchase” Instead of comparing sample means, we want to compare the percent in the “made a purchase” category to some expectatio...

Two - Sample T test

  2 Sample T-Test Suppose that a company has recently updated their website to make it more colorful and inviting. The company wants to know whether the new design is resulting in visitors staying on the site for a longer period of time. A sample of 100 visitors who saw the old design spent an average of 25 minutes on the site. A second sample of 100 visitors who saw the new version spent an average of 28 minutes on the site. Did the average time spent per visitor vary across groups? Or is this difference attributable to random chance? One way of testing whether this difference is significant is by using a  2 Sample T-Test . A 2 Sample T-Test compares two sets of numerical data. The null hypothesis of a 2 Sample T-Test is that the two observed samples come from populations with the same mean. In the example above, this means: if we could observe all site visitors in two alternate universes (one where they see each version of the site), the average visiting times in these unive...

Web Scraping using JSON and API

JSON–from the web to Python Wow, congrats! You've just queried your first API programmatically in Python and printed the text of the response to the shell. However, as you know, your response is actually a JSON, so you can do one step better and decode the JSON. You can then print the key-value pairs of the resulting dictionary. That's what you're going to do now! Pass the variable  url  to the  requests.get()  function in order to send the relevant request and catch the response, assigning the resultant response message to the variable  r . Apply the  json()  method to the response object  r  and store the resulting dictionary in the variable  json_data . # Import package import   requests # Assign URL to variable: url url  =  'http://www.omdbapi.com/?apikey=72bc447a&t=social+network' # Package the request, send the request and catch the...
