Histograms or frequency plots are indeed graphical tools used to understand variability (A), are typically constructed with data separated into a range of bars or sections (B), have a vertical axis representing frequency and a horizontal axis representing the scale of characteristics (C), and can resemble a bell shape if the data follows a normal distribution and is in control, though this is not always the case (D). Therefore, all the given statements are correct descriptions of histograms or frequency plots.
