Getting to a 36 ACT Math score isn't easy. It'll require perfection. But with hard work and my strategies below, you'll be able to do it. I've scored 36 on Math on all my ACTs, and I know what it takes.Follow my advice, and you'll get a perfect score—or get very close. ...
With your CSAT Question, you can then use the formula below to calculate the mean average of all the scores. CSAT Score (%) = (Sum of All Scores ÷ Sum of the Maximum Possible Scores) × 100 Example Let’s say that we asked our question to six customers and they gave us the follow...
What does that mean? Well, consider a triangle with two 70 degree angles. You’d infer that the third is 40, because that’s just the objective rule – the angles of a triangle add to 180. Similarly, if ‘Garfunkles are better suited for bulteration than are thrillpoppers, as thrill...
When CTC first appeared, due to the high difficulty of its training optimization and the more stringent requirements for the amount of data, the use of CTC at that time was a bit tricky. Such as ESSEN mentioned above, use CTC for training phonemes, and then still pick up WFST like every...

To solve for the mean of this data set, we will need to use all the information we’ve been given and will alsoneed to know what the mode and median are. As a reminder, the mode is the value that appears most frequently in a data set, while the median is the middle value in a...
A sample of 15 answer papers has a mean score of 85. Can we assume that these 15 scores come from the designated population? Solution Our task is to determine if this sample comes from the above mentioned population. How to solve this? We approach this problem by computing the standard ...
