Bar plot and proportion

mark · August 2020

(10 points)

Using your own random data from last Friday's forum question, let's use Colab to examine the activity_level variable. Specifically:

Generate a bar chart for activity_level and
Compute the proportion of folks whose activity level is high.

Note that creative burden is higher in this lab than in the last in that the Colab link above leads to a blank notebook. Nonetheless, you can find sample code that should help in our class presentation on Categorical Data.

patrickdimond · August 2020

I generated my own random data with this code:

import pandas as pd
df = pd.read_csv('https://www.marksmath.org/cgi-bin/random_data.csv?     username=pkdimond')
df.head()

My data:

first_name  last_name   age sex height  weight  income  activity_level
0   Retha   Reese   41  female  63.91   166.41  24811   moderate
1   Felicia Hamm    41  female  61.88   152.91  11829   high
2   Lauren  Poindexter  22  female  69.36   219.97  4259    none
3   Erin    Davis   29  female  60.52   224.19  19351   moderate
4   Minnie  Bouie   20  female  69.10   140.45  12624   high

I got my value counts with the code:

value_counts = df['activity_level'].value_counts()
value_counts.to_frame()

...and got:

activity_level
none    37
high    35
moderate    28

My proportion of people with a high activity level is .35

value_counts['high']/len(df)

I got my bar chart with this code:

value_counts.plot.bar(figsize=(12,7), rot = 0);

Here is my data set:

import pandas as pd
df = pd.read_csv('https://www.marksmath.org/cgi-bin/random_data.csv? 
username=jaallmer27')
df.head()

Here is the value counts, which are the data points for my bar chart

value_counts = df['activity_level'].value_counts()
value_counts

Here is my bar chart for activity level, obtained by

value_counts.plot.bar(figsize=(12,7), rot = 0);

I then computed the proportion of folks whose activity level is high, which is .33

value_counts['high']/len(df)

# Output: 0.33

value_counts = df['activity_level'].value_counts()

    activity_level
moderate    39
none    34
high    27

then i put the data into a bar graph

and i found who was high with this and got 0.27

John_South · August 2020

First I gather the data:

import pandas as pd
df = pd.read_csv('https://www.marksmath.org/cgi-bin/random_data.csv?username=jsouther')
df.head()

Then I take the value counts from the activity_level variable:

value_counts = df['activity_level'].value_counts()
value_counts.to_frame()

To get the bar chart, I just enter the following code to produce one:

value_counts.plot.bar()

Finally for the proportion data, I just enter this line which returned the value 0.34

value_counts['high']/len(df)

And that's all I need to put down.
