NEW QUESTION # 309
Which of the following query optimization techniques involves examining only the data that is needed for a particular task?
Answer: D
Explanation:
The correct answer is C. Indexing documents.
Indexing documents is a query optimization technique that involves creating a data structure that allows faster access to the data in the documents. Indexing documents can reduce the amount of data that needs to be scanned for a particular query, thus improving the performance and efficiency of the query. Indexing documents can also help with searching, sorting, filtering, and aggregating the data in the documents12

NEW QUESTION # 311
A data analyst is helping a retail store categorize its customers into five different groups based on the following information:
* How recently the customers made purchases
* How frequently the customers made purchases
* How much the customers spent
Given the following information:
Which of the following would be most important for the analysis?
Answer: C
NEW QUESTION # 312
Which of the following value is the measure of dispersion "range" between the scores of ten students in a test.
The scores of ten students in a test are 17, 23, 30, 36, 45, 51, 58, 66, 72, 77.
Answer: B
Explanation:
The correct answer is: 60
Range is the interval between the highest and the lowest score.
Range is a measure of variability or scatteredness of the varieties or observations among themselves and does not give an idea about the spread of the observations around some central value.
Symbolically R = Hs - Ls.
Where R = Range; Hs is the 'Highest score' and Ls is the Lowest Score.
The scores of ten students in a test are: 17, 23, 30, 36, 45, 51, 58, 66, 72, 77.
The highest score is 77 and the lowest score is 17.
So the range is the difference between these two scores Range = 77 - 17 = 60
NEW QUESTION # 313
An analyst is reviewing the following data:
Car IDSpeed
123155
566436
564418
650567
546436
645638
Which of the following should the analyst include in the measures of central tendency for speed?
Answer: D
Explanation:
The measures of central tendency include the mode, median, and mean. The mode is the value that appears most frequently in a data set. In this case, the speed of 36 appears twice, making it the mode. The median is the middle value when a data set is ordered from least to greatest; for these speeds, when ordered (18, 36, 36,
38, 55, 67), the median is the average of the two middle numbers, which is ( \frac{36 + 38}{2} = 37 ). The mean is the average of all values, calculated as ( \frac{55 + 36 + 18 + 67 + 36 + 38}{6} = 41.7 ).
References:
* The calculation of the mode, median, and mean is based on standard statistical formulas and definitions.
The measures of central tendency for speed include the mode, median, and mean. To calculate these, we first need to organize the data:
* Speeds in ascending order: 18, 36, 36, 38, 55, 67
* Mode is the value that appears most frequently, which is 36, as it appears twice.
* Median is the middle value when the data is ordered. Since we have an even number of observations, we take the average of the two middle values (36 and 38), resulting in 37.
* Mean is the sum of all values divided by the number of values. (18+36+36+38+55+67)/6=41.5 (18+36+36+38+55+67)/6=41.5.
Thus, the correct option is D, which includes Mode = 36, Median = 37, and Mean = 41.5. The range, maximum, and minimum values, although useful in understanding data dispersion, are not measures of central tendency and are therefore not relevant to this specific question.
