Interpret the given box plot and identify the median value: [insert box plot image here]

• The median value is at the upper whisker of the box plot

• The median value can be found at the line inside the box in the box plot.

• The median value is at the lower whisker of the box plot

• The median value is at the highest point of the box plot

Explain the concept of standard deviation and its significance in statistics

• Standard deviation is a measure of the amount of variation or dispersion of a set of values. It indicates how much the values deviate from the mean.

• Standard deviation is not important in statistics

• Standard deviation is used to calculate the median of a data set

• Standard deviation is a measure of central tendency in a set of values

Explain the concept of range and its importance in data analysis

• The range in data analysis refers to the difference between the highest and lowest values in a dataset. It is important because it provides a measure of the spread or variability of the data.

• The range in data analysis refers to the number of data points in a dataset. It is important because it provides a measure of the sample size.

• The range in data analysis refers to the difference between the mean and median of a dataset. It is important because it provides a measure of the data's distribution.

• The range in data analysis refers to the average of the highest and lowest values in a dataset. It is important because it provides a measure of the central tendency of the data.
