. During a test nine Grade 2 learners obtained the following scores out of 40 marks: 38, 23, 32, 40, 17, 23, 22, 16, 21.

Use the test scores to calculate the:
7.1 mode (2)

7.2 range of score (2)

7.3 median (2)

8. Explain the examples of suggested assessment tasks for left-brain learners. (4)

1 answer

Let’s begin with the calculations for the test scores of the nine Grade 2 learners.

7.1 Mode (2 marks)

The mode is the number that appears most frequently in a dataset.

Scores: 38, 23, 32, 40, 17, 23, 22, 16, 21

  • The scores given: 38, 23 (twice), 32, 40, 17, 23 (twice), 22, 16, 21.
  • The score that appears most frequently is 23.

Mode = 23

7.2 Range of Score (2 marks)

The range is calculated by subtracting the smallest score from the largest score.

Scores: 38, 23, 32, 40, 17, 23, 22, 16, 21

  • The highest score is 40.
  • The lowest score is 16.

Range = Highest Score - Lowest Score = 40 - 16 = 24

Range = 24

7.3 Median (2 marks)

To find the median, we need to organize the scores in ascending order and then find the middle value.

Ordered Scores: 16, 17, 21, 22, 23, 23, 32, 38, 40

Since there are 9 scores (an odd number), the median is the middle score, which is the 5th score in the ordered list.

Median = 23

8. Examples of Suggested Assessment Tasks for Left-Brain Learners (4 marks)

Left-brain learners are often characterized by their strengths in logical reasoning, analytical thinking, and the ability to focus on details. Here are some examples of assessment tasks that might suit their learning style:

  1. Mathematical Problem Solving:

    • Assign problems that involve logical reasoning, such as puzzles or word problems that require step-by-step solutions.

  2. Structured Writing Assignments:

    • Task students with writing reports or essays on specific topics with clear, organized structures. Provide outlines to guide them in their writing.

  3. Data Analysis Projects:

    • Provide a dataset and ask students to analyze it, create graphs or charts, and interpret the data. This could involve simple statistics or trends.

  4. Science Experiments with Detailed Procedures:

    • Engage left-brain learners with experiments that require careful planning, data collection, and analysis. Encourage them to follow precise methods and report their findings rigorously.

These tasks can leverage the analytical and systematic tendencies of left-brain learners, allowing them to demonstrate their abilities effectively.
