💼 Career

Knowing how to quickly get statistics from data using Measure-Object is useful for data analysis and reporting tasks in many IT and business roles.

1

Create daily sales data

Create an array called $dailySales with these exact values: 120, 150, 90, 200, 170.

PowerShell

# Create the array $dailySales with the given sales numbers
# Your code here

Need a hint?

Use @( ... ) to create an array in PowerShell.

2

Set high sales threshold

Create a variable called $highSalesThreshold and set it to 150.

PowerShell

$dailySales = @(120, 150, 90, 200, 170)
# Create the variable $highSalesThreshold and set it to 150
# Your code here

Need a hint?

Just assign the number 150 to the variable $highSalesThreshold.

3

Calculate sales statistics

Use Measure-Object with -Average, -Sum, -Minimum, -Maximum, and -Count on $dailySales. Store the result in a variable called $stats.

PowerShell

$dailySales = @(120, 150, 90, 200, 170)
$highSalesThreshold = 150
# Use Measure-Object on $dailySales and save to $stats
# Your code here

Need a hint?

Use the pipeline | to send $dailySales to Measure-Object with all the needed parameters.

4

Display the statistics

Print the count, sum, average, minimum, and maximum from $stats using Write-Output with clear labels.

PowerShell

$dailySales = @(120, 150, 90, 200, 170)
$highSalesThreshold = 150
$stats = $dailySales | Measure-Object -Average -Sum -Minimum -Maximum -Count
# Print the statistics with labels
# Your code here

Need a hint?

Use Write-Output and access properties like $stats.Count. Round the average to 2 decimals if needed.
