Smoothie Data You will be given a copy of this sheet which has the data you entered last week.

Smoothie Data On the back are the questions to remind you what they were. Section 1 - Buying Smoothies 1a - I am likely to be influenced by the range of flavours 1b - I am likely to be influenced by the price of the product 1c - I am likely to be influenced by the nutritional value of the product 1d - I am likely to be influenced by the type of packaging Section 2 - Nutrition 2a - I would be more likely to buy a low calorie smoothie 2b - I would be more likely to buy a low fat smoothie 2c - I would be more likely to buy a high protein smoothie 2d - I would be more likely to buy a low sugar smoothie Section 3 - Packaging 3a - I would be more likely to buy a smoothie if the packaging was an interesting shape 3b - I would be more likely to buy a smoothie if the packaging was bright and colourful 3c - I would be more likely to buy a smoothie if the packaging was environmentally friendly 3d - I would be more likely to buy a smoothie if the packaging was easy to use

Select one of the columns – such as Section 1 Column a You need to produce a frequency table like the one below which was mentioned at the end of last lesson Mark (out of 10) Frequency 0 to The frequency column should add up to 24

Step 1: Draw a Bar Chart Mark (out of 10) Frequency 0 to

Step 2: Draw a Pie Chart Mark (out of 10) FrequencyFractionAngle 0 to 544/244/24 x 360 = /243/24 x 360 = /248/24 x 360 = /243/24 x 360 = /242/24 x 360 = /244/24 x 360 = degrees

Step 2: Draw a Pie Chart

Step 3 – Calculate the Mean, Mode, Median & Range Using the list of 24 numbers, put them in order, starting with the smallest and find: Mean: Add up all the scores and divide by 24 Mode: Most Common Score Median: Middle Score Range: Largest score – Smallest score

Step 4 Repeat the process for another column
