# 1. Unit 1 – Data

## Unit Summary

• We aim to understand that different types of graphs have special purposes.
• We want to design surveys, collect, record, organise and display data in graphs using an electronic database.
• Identify, describe and explain central tendencies (median, mode, range and mean) in a set of data.

We have so far worked with Bar graphs and have moved to introduce histograms and use data to represent and analyse graphs. The students of 5S have been able to carry out an investigation that we have linked to our UOI – Conflict and Resolution. We have defined a problem about conflict disagreements in our school. We have gathered the data by using a Frequency chart. We have presented the data by selecting the correct graph – Histogram. We have analysed the data and then we have interpreted the findings. We have talked about the results and we are hoping to speak to the rest of the Grade 5 students about these findings and see how we can improve things in our school.

## WEEKS 5 – 6

We have been working hard on two pieces of assessments. Each student has been working with their own inquiries. This has enabled the students to investigate something of their interest. We have focused on representing, describing, explaining and analysing the data. We also looked at working out central tendencies. Their final work was of high quality and students were able to review their new learning effectively.

STEPS IN STATISTICAL INVESTIGATION

1. DEFINING THE PROBLEM

The main goal of the project we are involved in is to get some information about how we respond to disagreements and conflict in our lives. Then, you need to carry out a survey, and then you will need to analyze and draw conclusions from the data collected and represented.

 Question:

1. GATHERING RELEVANT INFORMATION
 Conflict Tally Marks Frequency

1. PRESENTING/ORGANIZING DATA

This step is for you to work out what is the best graph to use to represent your findings. Use the sheet provided by your teacher.

4.ANALYZING DATA

Here you need to analyse your graph and record what the graph is showing and ask yourself why this is happening? For example, what is the most common form of conflict within the playground, what makes people disagree easily and over what?

1. INTERPRETING RESULTS

With this step, we finish our project. This is the last step, but also, the most important point of our work and the reason for which we have carried out the surveys. It is the moment of drawing conclusions on what conflicts we have in our school and how we deal it with it. Looking at the tables we have made, we need to summarize the information, these tables contain only with two or three sentences, that is to say, only with the information we consider more important.

## Week 3

This week we have been working hard to learn new concepts when inquiring about DATA

We have introduced the concept of CENTRAL TENDENCIES (mode, median, range and mean). We have used a number of practical samples to learn how to calculate and learn more accurately about finding these tendencies.

We have used a number of tools to learn well how to determine these C. T. Here is a brief list of resources you could use to gain a better understanding of these tendencies.
