### Featured Range, Mean, Median and Mode Vocabulary Words On These Puzzles

**Cumulative Frequency** – Cumulative frequency is the running total of the frequencies of values in a dataset, usually presented in a tabular or graphical form. It enables the visualization of the distribution of values and the calculation of percentiles or cumulative percentages within the dataset.

**Frequency** – Frequency refers to the number of times a particular value occurs in a dataset or within a specific range. It is a fundamental concept in statistics and probability, providing information about the prevalence or occurrence of different outcomes or events.

**Geometric Mean** – Geometric mean is a measure of central tendency calculated by taking the nth root of the product of n values in a dataset. It is commonly used for calculating average rates of change or growth, especially in financial and scientific contexts, where values are proportional or exhibit exponential growth.

**Harmonic Mean** – Harmonic mean is a measure of central tendency calculated by dividing the number of values in a dataset by the reciprocal of each value, then taking the reciprocal of the resulting sum. It is commonly used for averaging rates or ratios, providing a balanced measure that accounts for variability in the data.

**Histogram** – A histogram is a graphical representation of the distribution of numerical data, where bars of varying heights depict the frequency of occurrence of different value ranges. It provides a visual summary of the data’s distribution, making it easier to identify patterns, trends, and outliers.

**Interquartile Range (IQR)** – Interquartile range is a measure of statistical dispersion, calculated as the difference between the upper quartile (Q3) and the lower quartile (Q1) in a dataset. It provides insights into the spread of the middle 50% of the data and is less affected by extreme values compared to the range.

**Kurtosis** – Kurtosis is a measure of the “tailedness” of the probability distribution of a real-valued random variable. It quantifies the degree to which the distribution is peaked or flattened compared to a normal distribution, providing insights into the presence of outliers or extreme values.

**Mean** – Mean, also known as the average, is a measure of central tendency calculated by summing all values in a dataset and dividing by the total number of values. It represents the typical value of the dataset and is sensitive to extreme values, making it useful for describing the central position of the data.

**Mean Absolute Deviation (MAD)** – Mean absolute deviation is a measure of dispersion that calculates the average absolute difference between each data point and the mean of the dataset. It provides insights into the average variability or spread of the data points around the mean, regardless of the direction of deviation.

**Mean Squared Error (MSE)** – Mean squared error is a measure of the average squared difference between predicted and observed values in a dataset. It is commonly used in regression analysis to evaluate the accuracy of predictive models and quantify the extent of prediction errors.

**Median** – Median is a measure of central tendency that represents the middle value in a dataset when arranged in ascending order. Unlike the mean, the median is less affected by extreme values and provides a more robust estimate of the central position of the data, especially in skewed distributions.

**Median Absolute Deviation (MAD)** – Median absolute deviation is a robust measure of dispersion that calculates the median of the absolute differences between each data point and the median of the dataset. It provides insights into the variability or spread of the data points around the median, especially in datasets with outliers or non-normal distributions.

**Mode** – Mode is the value that appears most frequently in a dataset. It provides information about the most common or typical value in the dataset and is useful for identifying peaks or clusters within the data distribution, especially in categorical or discrete datasets.

**Mode of Central Tendency** – Mode of central tendency refers to the value in a dataset that occurs with the highest frequency. It represents the most common or typical value and is useful for summarizing categorical or discrete data, identifying peaks or clusters within the distribution, and understanding the dominant characteristics of the dataset.

**Mode Imputation** – Mode imputation is a data preprocessing technique used to replace missing values in a dataset with the mode, or most frequently occurring value, of the respective variable. It helps maintain the integrity of the dataset and ensures completeness for subsequent analyses, especially in cases where missing values are minimal.

**Outlier** – An outlier is a data point that significantly deviates from the rest of the observations in a dataset. Outliers can arise due to measurement errors, sampling variability, or genuine differences in the underlying process, and they may have a substantial impact on statistical analyses and interpretations.

**Percentile** – A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a dataset falls. For example, the 25th percentile represents the value below which 25% of the data points lie, providing insights into the distribution of values within the dataset.

**Quartile** – Quartiles are values that divide a dataset into four equal parts, each containing 25% of the data points. The first quartile (Q1) represents the 25th percentile, the second quartile (Q2) is the median, and the third quartile (Q3) represents the 75th percentile.

**Range** – Range refers to the difference between the highest and lowest values in a dataset. It provides a measure of the variability or spread of the data points and is useful for understanding the extent of dispersion within the dataset.

**Skewness** – Skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable. It indicates whether the data is skewed to the left (negative skew) or to the right (positive skew) relative to the mean, affecting the shape and interpretation of the distribution.

**Standard Deviation** – Standard deviation is a measure of the dispersion or spread of a set of values from its mean. It quantifies the average distance of individual data points from the mean and provides insights into the variability or consistency of the data, with larger standard deviations indicating greater variability.

**Trimmed Mean** – Trimmed mean is a measure of central tendency that calculates the mean of a dataset after removing a specified percentage of extreme values from both ends of the distribution. It helps mitigate the impact of outliers on the mean, providing a more robust estimate of the central position of the data.

**Variance** – Variance measures the average squared deviation of each data point from the mean of the dataset. It provides a measure of the dispersion or spread of the data points around the mean and is commonly used in statistical analysis to quantify the variability within a dataset.

**Weighted Mean** – Weighted mean is a measure of central tendency that takes into account the relative importance or weight of each data point in a dataset. It is calculated by multiplying each value by its respective weight, summing the products, and dividing by the total weight, providing a more accurate representation of the central tendency, especially in datasets with unequal weights.

**Weighted Median** – Weighted median is a measure of central tendency that takes into account the relative importance or weight of each data point in a dataset. It is calculated by sorting the weighted data points and identifying the value that corresponds to the cumulative weight exceeding 50%, providing a robust estimate of the central position of the data.
