1. An analyst is arranging all data in a dataset by ranking it based on a specific metric to make it easier to understand, analyze, and visualize. Which task is the analyst performing?
A. Updating the data
B. Sorting the data Correct
C. Restricting access to the data
D. Filtering the data
Explanation
Sorting involves arranging data based on a specific metric, such as ranking, to enhance understanding and visualization. Updating modifies data values, restricting access limits who can view it, and filtering selects specific data subsets.
2. An analyst wants to sort all columns in a table in Microsoft Excel using Structured Query Language (SQL). Which SQL command can the analyst use to sort all columns?
A. CAST
B. SELECT * Correct
C. WHERE =
D. JOIN
Explanation
The SELECT * command retrieves all columns from a table, and when combined with ORDER BY, it sorts the data. CAST converts data types, WHERE filters rows, and JOIN combines tables, none of which directly sort columns.
3. Which tool does an analyst use to organize similar kinds of data into categories and subject areas?
A. Tables Correct
B. Reports
C. Charts
D. Maps
Explanation
Tables organize data into categories and subject areas using rows and columns for structured analysis. Reports summarize data, charts visualize trends, and maps display geographic data, but tables are primary for organization.
4. How does an analyst type a SORT function in Microsoft Excel to organize data by a certain category?
A. {=-SORT]
B. [=+SORT}
C. {=SORT] Correct
D. SORT *
Explanation
In Excel, the SORT function is typed as =SORT to organize data by a specified category. The other options (-SORT, +SORT, SORT *) are not valid Excel function syntax.
5. How would an analyst specify a descending order of data in a Structured Query Language (SQL) query?
A. ORDER BY followed by DESC Correct
B. FROM followed by database
C. SORT followed by TRUE
D. FILTER followed by ASC
Explanation
In SQL, ORDER BY followed by DESC specifies descending order for sorting data. FROM selects the table, SORT and FILTER are not SQL commands, and ASC denotes ascending order.
