INTRODUCTION
Data analysis includes statistical tools and techniques which in turn help in analyzing
numeric facts & figures effectually. Statistical tools are highly significant as it helps in
evaluating present and making forecast about future. For this project report Lewisham of
London has been selected. This study will provide insight about weather condition in terms
of wind speed pertaining to Lewisham.
1. Arranging data in a structured format
Data of Lewisham wind speed (10 consecutive days) from 30th September to 9th October is

3. Calculating descriptive statistics of Lewisham wind speed data and showing steps of
calculation
i. Mean
Step 1: Firstly, need to determine the number of observation
Step 2: Total of wind speed (km/hr) pertaining to 10 days are calculated
Step 3: At this stage, mean value can be determined by dividing ∑X from n (Sclove, 2018)
