How do you find the mode of a set of numbers?

Identify the number(s) with the highest frequency in the set.

Add all numbers and divide by the total count.

Select the smallest number in the set.

Choose the number with the lowest frequency.

If the data set has an odd number of values, how do you find the median?

Arrange the values in ascending order and select the middle value as the median.

Add all values and divide by the number of values

Select the first value as the median

Multiply all values and divide by the number of values

Explain the concept of quartiles in relation to finding the IQR.

The concept of quartiles helps in finding the IQR by identifying the range where the middle 50% of the data lies.

IQR is calculated by adding the quartiles together

Quartiles divide the data into 10 equal parts

Quartiles are used to find the mean of a dataset

What is the significance of the range in a data set?

The range in a data set signifies the spread or variability of the data.

The range indicates the most common value in the data set.

The range is used to determine the shape of the data distribution.

The range represents the sum of all values in the data set.

Why is the median sometimes preferred over the mean as a measure of central tendency?

The median is not influenced by extreme values.

The median is not affected by the sample size.

The median is calculated differently in various contexts.

The median is always smaller than the mean.

In a data set with multiple modes, how is the mode calculated?

Identify the value that appears most frequently in the data set.

Select the smallest value in the data set.

Choose the value that appears least frequently in the data set.

Calculate the average of all values in the data set.

How does an outlier affect the calculation of the mean in a data set?

The outlier can make the mean either higher or lower than it would be without the outlier.

The outlier always decreases the mean

The outlier always increases the mean

The outlier has no impact on the mean calculation

Explain the difference between the mean and the median in terms of outliers.

The mean is heavily influenced by outliers, while the median is not affected by outliers.

Both the mean and the median are equally influenced by outliers.

The mean and the median are both unaffected by outliers.

The mean is not affected by outliers, while the median is heavily influenced by outliers.

What is the relationship between the IQR and the spread of data in a box plot?

The IQR is directly related to the spread of data in a box plot.

The IQR is only related to the median in a box plot.

The IQR is inversely related to the spread of data in a box plot.

The IQR has no impact on the spread of data in a box plot.
