Histograms: Histograms are graphical representations of data distribution using bars. They display continuous data grouped into intervals on the x-axis and their corresponding frequencies on the y-axis.
Relative Frequency: Relative frequency refers to the proportion or percentage of times an event occurs compared to the total number of observations. In a frequency table, relative frequencies can be calculated by dividing each frequency by the total number of observations.
Mode: In statistics, mode represents the value(s) that occur with the highest frequency in a dataset. In a frequency table, it is easy to identify modes as they correspond to values with maximum frequencies.
