# Course 1 – Data, Data, Everywhere quiz Answers

## table of CONTENT

Data analysts balance many different roles in their work. In this part of the course, you’ll learn about some of these roles and the key skills used by analysts. You’ll also explore analytical thinking and how it relates to data-driven decision-making.

## Learning Objectives

• Explain the concept of data-driven decision-making including specific examples
• Describe the key characteristics of analytical thinking
• Conduct an analytical thinking self assessment, giving specific examples of the application of analytical thinking
• Demonstrate an understanding of the five key analytical skills used by data analysts
• Explain how analytical thinking enables decision-making
• Begin asking more effective questions

### Identify the pattern from left to right in the set of blocks below and try to predict which block should replace the block with the question mark.

(Correct)

Correct: This is the missing block. The pattern of the dots increases by one in each block. Therefore, the best answer has five dots.

### Based on the images above, which option comes next in the pattern?

Correct: The triangle with 2 dots is the next image in the sequence based on two patterns present in the series: the number of sides and the number of dots. Moving from left to right, both decrease by one. Given these patterns, if the previous block contained a shape with four sides and three dots, then the next shape should have three sides and two dots.

### Fill in the blank: 9, 13, 17, 21, 25, 29, _____

• 10
• 25
• 33 (Correct)
• 55

Correct: The correct answer is 33. The pattern of numbers are all increasing, and the difference between each number is 4.

### Fill in the blank: 4, 9, 16, 25, 36, 49, _____

• 30
• 64 (Correct)
• 81
• 62

Correct: The next number in the series is 64. There are two patterns in the sequence. One is that each number is squared and then the number being squared is increased by one (e.g., 2², 3², 4², 5², 6², 7²). The second pattern is in the difference between the numbers in the sequence: 9 – 4 = 5, 16 – 9 = 7, 25 – 16 = 9, and so on.

### Select the image below that completes the statement.

(Correct)

Correct: This image completes the statement. The first image in the statement is reflected in the second image. To complete the analogy, the answer would be an image that is a side-by-side reflection of the third image.

### Which image completes it?

(Correct)

Correct: Since the pattern in the first image was rotated 90 degrees counter-clockwise, this image completes the statement.

### Fill in the blank: A1, B3, C5, D7, E9, F11, G13, _____

• H15 (Correct)
• D17
• J15
• H16

Correct: The patterns of this series are the letters listed alphabetically and the numbers increasing by two with each new set. Therefore, following that pattern, the next code would be H15.

### Fill in the blank: A, AA, AAA, B, BA, BAA, BAAA, BB, BBA, BBAA, BBAAA, BBB, _____

• BBBA (Correct)
• BBAA
• BBAAA
• BBBB

Correct: The pattern in this sequence follows the letter A. A is added until there are three As, which is when the letter B takes the place of the previous As, and the pattern continues. Therefore, BBBA is next in the series.

### 9. Now, identify patterns in a word problem using a data visualization. There are 12 chocolates in a box: eight have caramel filling, six have coconut filling, and two have both caramel and coconut filling. Choose the best image that describes this box of chocolates.

(Correct)

Correct: This diagram depicts six chocolates with caramel filling only, four chocolates with coconut filling only, two chocolates with both caramel and coconut filling, and the total number of chocolates is 12.

### Find out how many children have sandwiches with neither peanut butter nor jelly and choose the image that describes the situation best.

(Correct)

Correct: In this diagram, there are six sandwiches with jelly, five sandwiches with peanut butter, and three sandwiches with both. This means that there are (5 + 6 – 3 = 8 ) eight sandwiches with either peanut butter or jelly. There are a total of 10 children. Consider: 10 – 8 = 2. This means two children have neither peanut butter nor jelly in their sandwiches.
