PPMNB-085 JAV example, we need to calculate the average time between tweet messages as the first step. Here’s the list of tweets in 2017: - Jan/23/2017 - Jan/03/2017 - Feb/09/2017 - Feb/14/2017 - Feb/15/2017 - Mar/31/2017 - Apr/16/2017 - Apr/25/2017 - May/26/2017 - June/21/2017 - June/23/2017 - July/06/2017 - July/26/2017 - July/30/2017 - July/31/2017 - Aug/01/2012017 - Aug/09/2017 - Aug/31/2017 - Sep/01/2017 - Sep/06/2017 - Sep/06/2017 - Sep/12/2012017 - Sep/30/2017 - Oct/12/2017 - Oct/31/2017 - Nov/09/2017 - Nov/13/2017 - Dec/12/2017 - Dec/18/2017 - Dec/13/2017 - Dec/16/2017 - Dec/19/2017 - Dec/23/2017 - Dec/31/2017 We need to calculate the average time between tweets. First, determine all the differences between tweets in one year. Then, sum all the differences and divide by the number of tweets minus one to determine the average. ### Step 1: Calculate the differences between messages. Determine all the differences between one tweet and the next one. How to Calculate? Here’s the procedure: 1. Select the date of the tweet. 2. Record the date of the next tweet. 3. Calculate the number of days in between one tweet and the next. Simply assume that the current time is Jan 1st 2017. So, the first tweet was in Jan 3rd 2017. Then, the second tweet was in Jan 23rd 2017. Calculate the difference between the second and the first tweet (20 days). The third tweet was in Feb 9th 2017. Calculate the difference between the third and the second tweet (37 days). And so on... Make a list of all the differences between tweets. From the order of events: (latest goes last) - 1: February/25 - 2: February/26 - 3: March/17 - 4: May/15 - 5: May/20 - 6: June/18 - 7: July/10 - 8: August/13 - 9: September/19 1. 2017/02/25 2. 2017/02/26 3. 2017/03/17 4. 2017/05/15 5. 2017/05/20 6: 2017/06/18 7: 2017/07/10 8: 2017/08/13 9: 2017/09/19 ### Step 2: Calculate the average time between tweets. Sum all the differences and divide by the number of tweets minus one to determine the average. Have you observed that the numbers are disproportionate? Well, they are. The largest difference is 86 days, whereas the smallest difference is 1 day. Hence, the average time between tweets would be the total number of days divided by the number of tweets minus one. See if this sheds any meaning on the matter. Since we have 9 tweets, there are 8 differences. Here’s the list of differences: 20, 37, 81, 5, 29, 22, 21, 41 Sum up all the differences. 20 + 37 + 81 + 5 + 29 + 21 + 22 + 41 = 248 The total of all differences is 248. Divide sum by the number of tweets minus one to determine the average. 044/8 = 31 Determine average time between tweets is 31. Note: Be careful with your math if you’re doing this by yourself. ## I’m making a mining calculator in my game World Life. The first step is to mine 500 rock.
