What is the primary purpose of identifying and removing outliers from a dataset when analyzing statistics like mean, median, and range?

• To reduce the number of data points for easier calculations

• To ensure the histogram becomes symmetrical

• To minimize the distortion of the mean and improve accuracy in interpretation

• To remove values that fall outside the range of the histogram

In a histogram showing the prices of used cars, most of the data is concentrated on the left (lower prices), with a few higher prices creating a long tail to the right. What type of data distribution does this describe?

• Symmetrical Distribution

• Left-skewed (Negative Skew)

• Right-skewed (Positive Skew)

• Normal Distribution

HISTOGRAM:

A dataset of used car prices includes the following values (in dollars): 18000, 18500, 19000, 19500, 20000, 20500, 21000, 22000, 23000, 24000, 25000, 26000, 27000, 28000, 29000, 30000, 60000, 65000.

Identify Outliers: Use the threshold formulas.

Which prices are considered outliers?

Recalculate Statistics Without Outliers: Calculate the new mean and median after removing the outliers.

• Outliers:

  $60,000 and $65,000;

  New Mean: $24,541; New Median: $24,000

• Outliers: $65,000; New Mean: $25,839; New Median: $24,000

• Outliers:

  $60,000 and $65,000;

  New Mean: $23,156.25; New Median: $22,500

• Outliers: $60,000; New Mean: $25,303 New Median: $25,000

BOX PLOT:

A dataset contains the following values in dollars: 45000, 47000, 48000, 50000, 51000, 53000, 55000, 58000, 60000, 62000, 65000, 130000.

Using this data: Calculate Q1, Q2 (Median), Q3, and the IQR.

Determine the lower and upper fences using the IQR.

Identify the outliers.

• Q1: $48,500; Q2: $55,000; Q3: $60,500; IQR: $12,000; Outliers: $130,000

• Q1: $49,000; Q2: $54,000; Q3: $61,000; IQR: $12,000; Outliers: $130,000

• Q1: $47,500; Q2: $51,000; Q3: $60,000; IQR: $12,500; Outliers: None

• Q1: $47,000; Q2: $55,000; Q3: $62,000; IQR: $15,000; Outliers: None
