Question

match the words and their descriptions: iqr mean, median and mode normal, skewed left and skewed right standard deviation, interquartile range, range spread three common descriptions of shape also called variability middle 50% of datas range measures of spread measures of center

Explanation:

1. IQR: The Interquartile Range (IQR) is calculated as \( Q_3 - Q_1 \), which represents the range of the middle 50% of the data. So it matches "Middle 50% of data’s range".
2. Mean, Median and Mode: These are the three most common measures of central tendency (or center) of a dataset. So they match "Measures of center".
3. Normal, skewed left and skewed right: These are three common descriptions of the shape of a distribution (how the data is distributed). So they match "Three common descriptions of shape".
4. Standard Deviation, Interquartile Range, Range: These are all measures that describe the spread (or variability) of a dataset. So they match "Measures of Spread" (and also "Also called variability" since spread is another term for variability).
5. Spread: Spread in statistics refers to the variability or dispersion of data, and terms like standard deviation, IQR, range are measures of spread. Also, spread is another name for variability. So it matches "Also called variability" and is related to the measures of spread.

Answer:

• IQR: Middle 50% of data’s range
• Mean, Median and Mode: Measures of center
• Normal, skewed left and skewed right: Three common descriptions of shape
• Standard Deviation, Interquartile Range, Range: Measures of Spread (Also called variability)
• Spread: Also called variability (and related to Measures of Spread)
