WebLearning Objective. To learn to interpret the meaning of three graphical representations of sets of data: stem and leaf diagrams, frequency histograms, and relative frequency histograms. A well-known adage is that “a picture is worth a thousand words.”. This saying proves true when it comes to presenting statistical information in a data set. WebApr 11, 2024 · The number of times a wave repeat is a frequency, denoted by f. We know that distance is equal to the speed over time, the same goes for the wave speed: v (wave speed) = λ/t. Also, we know that the frequency is 1/t, putting this value in the above equation: v = fλ. This is the required equation linking wave speed frequency and wavelength. how much turkey do i need for 15 people
