How to find frequency.

Complete the frequency table. Go along the data set and for each item put a tally mark in the table. When you have finished, add up the tally marks to find the frequencies. Add up the frequencies in the final column to get the total number of items in the data set. Frequency (statistics) For other uses, see Frequency (disambiguation). In statistics, the frequency or absolute frequency of an event is the number of times the observation has occurred/recorded in an experiment or study. [1] : 12–19 These frequencies are often depicted graphically or in tabular form. We can start with our equation that relates frequency, wavelength, and the speed of light. c = λ ν. Next, we rearrange the equation to solve for wavelength. λ = c ν. Lastly, we plug in our given values and solve. λ = 3.00 × 10 8 m s 1.5 × 10 14 1 s = 2.00 × 10 − 6 m. Currently this is what I am using to find frequency of dates in week intervals, by counting the results of the new dataset. However as you can imagine this is a slow process. I was wondering if there is a more automated and more effective way of doing this. Thank you! View solution in original post. 0 Likes
