You have a dataset with two variables: temperature and sales. You want to visualize if higher temperature affects sales. Which MATLAB approach best reveals this pattern?

hard📝 Application Q15 of 15

MATLAB - 2D Plotting

AUse a bar chart with sales only, no temperature data.

BUse a scatter plot with temperature on x-axis and sales on y-axis, add labels and title.

CPrint the data values in the command window without plotting.

DUse a pie chart to show temperature distribution.

Step-by-Step Solution

Solution:

Step 1: Choose visualization type for relationship
A scatter plot shows how two variables relate by plotting points for each pair.
Step 2: Add labels and title for clarity
Labels and title help understand what the axes represent and what the plot shows.
Step 3: Evaluate other options
Bar chart without temperature, printing data, or pie chart do not reveal the relationship between temperature and sales clearly.
Final Answer:
Use a scatter plot with temperature on x-axis and sales on y-axis, add labels and title. -> Option B
Quick Check:
Scatter plot reveals variable relationship = A [OK]

Quick Trick: Scatter plot shows relation between two variables [OK]

Common Mistakes:

Using bar or pie charts for relationships
Not labeling axes and title
Assuming printing data reveals patterns
