| Descriptive Statistics | This refers to the analysis of data that helps describe |
| Mean | The average of a set of values |
| Median | The middle value in a set of values |
| Mode | The value that appears most frequently in a set of data. A set of data may have one mode |
| Variability | A measure of how much the values in a data set are likely to differ from each other. Variability includes range |
| Range | The difference between the highest and lowest values in a dataset. |
| Standard Deviation | A measure of how spread-out numbers are from the mean |
| Variance | A statistical measurement of the spread between numbers in a data set. It's the average of the squared differences from the mean. |
| Bar Chart | A type of chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. |
| Pie Chart | A circular statistical graphic which is divided into slices to illustrate numerical proportion. Each slice of the pie represents a category. |
| Infographics | Visual representations of information |
| Frequency Distribution | A list |
| Percentile Rank | The percentage of scores in its frequency distribution that are equal to or lower than it. |
| Quartiles | Divide a rank-ordered dataset into four equal parts. |
| First Quartile (Q1) | Also known as the lower quartile |
| Second Quartile (Q2) | This is the median of a dataset. Half the numbers in the dataset are less than the median and half the numbers are greater. |
| Third Quartile (Q3) | Also known as the upper quartile |
| The Interquartile Range (IQR) | Calculated as Q3 - Q1 and represents the range within which the middle 50% of the values in the dataset lie. This can help you understand the dispersion or spread of your data. |
