I need to add new columns called 'Volume % Change', and "Close % Change" for this dataframe in PYTHON. The formula for Volume % Change is (Current day volume-previous day volume)/previous day volume The formula for Close % Change is (Current day Close - previous day)/previous day Close The output is like the attached image. Please assist! Thanks

There have been several actors who have played the titular character in the British sci-fi series Doctor Who since the show began in the early 1960s. In 2005 the series was rebooted and Christopher Eccleston, David Tennant, Matt Smith, Peter Capaldi, and Jodie Whittaker have all played the Doctor since. Several Whovians (fans of the show) were asked to rank the actors of the Doctor from their favorite to their least favorite. The results are in the preference schedule below using the initials of each actor (so CE = Christopher Eccleston; DT = David Tennant; etc.). 6. 8 12 16 17 18 23 20 1st Choice DT DT DT MS MS PC JW CE 2nd Choice CE PC PC JW CE JW CE MS 3rd Choice JW СЕ JW CE DT DT PC DT 4th Choice PC MS JW MS PC PC DT PC MS CE DT JW MS MS 5th Choice JW a.

If so, what are they? If not, why not? Do you believe it would help to create additional attributes during normalization? If so, what are they? If not, justify why it's not needed.

Sort the reaction times from smallest to largest located under the data tab. 2. Label the next two columns 'cumulative %' and 'count' respectively. 3. In the count' column fill in '1' in the first cell, '2' in the second, '3' in the third and so forth. It helps to use a formula. Ex. in cell C2 use the formula =C1+1 and then you can drag down. In the 'cumulative %' column, calculate the percentage as the =count/(total number of points). So for the first cell, 'B2', you would have =C2/10 since there are 10 data points in this example. Note: the last cell should always equal one because at the end all of the cells or 100% of the observations are accounted for. 4. Lastly, highlight the reaction time (x-axis) and cumulative % (y-axis) columns and make a scatter plot.
