How do I determine statistical relationship between two series <

If the "two series" are time sequence data, e.g., monthly sales and monthly
advertising over several years, start with a Line chart showing the two
series.

If the "two series" are cross-sectional data, e.g., productivity-units and
hours-of-training for each member of a group during a single time period,
start with an XY (Scatter) chart. Then add a trendline or use worksheet
functions like CORREL to obtain summary measures.
