This tool will construct a frequency distribution table, providing a snapshot view of the characteristics of a dataset. The calculator will also spit out a number of other descriptors of your data - mean, median, skewness, and so on.
First Quantile, third Quantile and Interquantile Range. Example: The following table gives the frequency distribution of the number of orders received each day during the past 50 days at the office of a mail-order company. Calculate the mean. Number f of order. X is the midpoint of the class. It is adding the class limits and divide by 2.
We use frequency tables to find descriptive statistics. These are values which help describe the set of data such as the mean, median and mode of a set of data. For example, A frequency table showing the ages of 25 25 students on a college course. The mode is 18 18. The median is the 13th 13th value which is 18 18.
