In statistics, the mode is a measure of central tendency representing the most frequently occurring value in a data set. For example, if we have the following numbers: 10, 11, 14, 9, 6, 10, the mode would be 10 since it is the most frequently occurring value. To find the mode of a set of numbers,
The median is a measure of central tendency used to describe a dataset’s middle value. The median is the middle value if the dataset has an odd number of values. If the dataset has an even number of values, the median is the average of the two middle values. The formula for calculating the median of
Descriptive statistics is a branch of statistics used to summarize and describe the characteristics of a dataset. Descriptive statistics involves calculating summary measures, such as the mean, median, mode, quantiles (generally quartile), range, interquartile range, standard deviation, and variance and using visualizations, such as histograms and scatter plots, to understand the distribution and patterns in
Descriptive and inferential statistics are two main branches of statistics that are used to analyze and interpret data. Descriptive statistics is a branch of statistics used to summarize and describe the characteristics of a dataset. Descriptive statistics involves calculating summary measures, such as the mean, median, mode, range, standard deviation, variance, inter-quartile range (IQR) and using
Sampling is the process of selecting a subset of data from a larger dataset. Sampling is often used in statistics and research to make inferences about a population based on a smaller sample of data. There are several reasons why sampling is essential and necessary in many research and data analysis applications:Sampling allows researchers to
