The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

We create buckets for different ranges of cherries, count the pies in each, and can answer questions about our pie inventory and cherry distribution! video https://cdn.kastatic.org/googleusercontent/zWWHq13-TqhJUcs2tlySsaLRxk1CnI4Mf1ubsEsXuMY1mzlELLyJFJdPqyXdyiN2o6BtUUBCWyDWOMHM3FttqZ9ZkQ Interpreting a histogram In a cherry pie store, we use a histogram to understand the distribution of cherries on pies.

In a histogram, each bar groups numbers into ranges. Taller bars show that more data falls in that range. A histogram displays the shape and spread of continuous sample data.  video https://cdn.kastatic.org/googleusercontent/RhHZWxwp22klKK7rm1TFYt9jpKrXxJkTLB4FLjHfv8LJ0AgOm6QxlTjAInvDKvKnBD3Zor4r_GAwsRFpJ_P1TvQ Creating a histogram A histogram is a graphical display of data using bars of different heights.
