Applications (3) 

Get current polling for the 2024 election and group all the polls by pollster and population, then split by polling date:

For each date, find a single value for each candidate. The Min will use many-candidate results over two-candidate results:

In[13]:=

Out[14]=

Create time series from the data, eliminating pollsters without recent or many polls:

In[15]:=

Out[16]=

Plot all the series:

In[17]:=

Out[17]=

Take a simple average over the pollsters at regular intervals and plot the result:

Possible Issues (3) 

The 2020 data includes numbers adjusted for convention bounces:

In[79]:=

Out[80]=

The bounce-adjusted numbers differ considerably from the standard average:

In[81]:=

Out[81]=

Use only non-bounce-adjusted values instead:

In[82]:=

Out[82]=
