Introduction

This session introduces working with data. At the conclusion of the lesson you will:

• understand terms, phrases, and concepts in data analysis;

• identify and use best practice in data structures.

Why Data?

We make decisions every day. Sometimes these are very small ones that don't require much consideration, or that come naturally through professional experience. But making the right decisions is key to our roles and the people we are trying to help. There are many aspects to decision-making that we always try to take into account. What's the ethical thing to do? Is it legal? Is it possible? Can we afford it? Is it supported by data?

Think of some example library-based decisions:

• amount spent on different types of stock;

• fines for overdue items;

• hire charges;

• staff levels in a library at different times;

• van routes and frequencies to move items between branches;

• stock to have in different libraries;

• opening hours;

How often are these fully informed by analysis of data and evidence?

Data is essential to decision-making, but even when data is available to us, we don't necessarily have the skills to interpret it, or manipulate it in the way we need to. But you don't need to be a data scientist to gain confidence in using data. This session aims to discuss data tasks we all deal with, and gain practice in some data manipulation techniques.
