  Describing Categorical Data - Frequency distributions Certainly! Here is a step-by-step guide to generating a frequency distribution table on Google Sheets: Open Google Sheets: Go to sheets.google.com and create a new or open an existing spreadsheet. Enter Data: In a column, enter the data values for which you want to create a frequency distribution. For example, let's say you have a dataset of exam scores and you want to create a frequency distribution for the scores. Sort Data: To ensure accurate frequency counts, it is helpful to sort the data in ascending or descending order. Select the column of data, go to the "Data" menu, and choose "Sort sheet by column [column letter]." This will arrange the data in the selected column in the desired order. Create Bins: Based on the range of values in your dataset, determine the appropriate bins or intervals for grouping the values. For example, if your exam scores range from 0 to 100, you can create bins of 10, such

week 1  Descriptive Statistics: Descriptive statistics is a branch of statistics that involves summarizing and presenting data in a meaningful way. It focuses on describing the main characteristics of a dataset without making inferences or generalizations about a larger population. Descriptive statistics provide a clear and concise summary of data, allowing researchers and analysts to understand and interpret the information. Common measures used in descriptive statistics include: Measures of Central Tendency:    Mean: The arithmetic average of a set of values.    Median: The middle value in a sorted dataset.    Mode: The most frequently occurring value in a dataset. Measures of Dispersion:    Range: The difference between the maximum and minimum values in a dataset.    Variance: The average of the squared differences from the mean.    Standard Deviation: The square root of the variance, providing a measure of the spread of data around the mean. Measures of Shape:    Skewness: A measur
