Question

3.3 ranking: quartiles, iqr and outliers
match the words and their descriptions:
min, q1, median, q3 and max
spread
normal, skewed left and skewed right
second quartile
mean, median and mode
iqr

Explanation:

1. Min, Q1, Median, Q3 and Max: These are key - values in a five - number summary that gives an overview of a data set's distribution.
2. Spread: It measures how far apart data values are, often related to range or inter - quartile range.
3. Normal, skewed left and skewed right: These describe the shape of a data distribution. In a normal distribution, data is symmetric; in a skewed left distribution, the tail is on the left side; in a skewed right distribution, the tail is on the right side.
4. Second quartile: The second quartile is the same as the median, which divides the data set into two halves.
5. Mean, Median and Mode: These are measures of central tendency. The mean is the average value, the median is the middle value when data is ordered, and the mode is the most frequently occurring value.
6. IQR: Inter - Quartile Range is the difference between the third quartile (Q3) and the first quartile (Q1), and it represents the middle 50% of the data.

Answer:

1. Five - number summary
2. Measure of dispersion
3. Distribution shapes
4. Median
5. Measures of central tendency
6. Q3 - Q1
