STEP 1

Assumptions1. Categorical data is qualitative and describes categories or groups. It can be nominal (like names, without any order) or ordinal (like ranks or scales with order). . Numerical data is quantitative and expresses a certain quantity, amount or range. It can be discrete (like number of apples) or continuous (like height, weight, temperature).

STEP 2

Now, let's classify each of the CensusAtSchool question topics into either categorical or numerical data.

STEP 3

"Amount of money earned last week" - This is a quantity and hence, it is numerical data.

STEP 4

"Arm span" - This is a measurement and hence, it is numerical data.

STEP 5

"Birthdate" - This is a date and can be considered as numerical data as it can be represented in a numerical format (like YYYYMMDD).

STEP 6

"Concentration exercise (seconds)" - This is a measurement of time and hence, it is numerical data.

STEP 7

"Dominant hand reaction time" - This is a measurement of time and hence, it is numerical data.

STEP 8

"Favourite sport" - This is a preference and hence, it is categorical data.

STEP 9

"Height" - This is a measurement and hence, it is numerical data.

STEP 10

"Hours slept per night" - This is a measurement of time and hence, it is numerical data.

STEP 11

"Language mostly spoken at home" - This is a type and hence, it is categorical data.

STEP 12

"Foot length" - This is a measurement and hence, it is numerical data.

STEP 13

"Opinions on environmental conservation" - This is a preference and hence, it is categorical data.

STEP 14

"School post code" - This is a type of identifier and hence, it is categorical data.

STEP 15

"State/Territory live in" - This is a type of location and hence, it is categorical data.

STEP 16

"Travel method to school" - This is a type of method and hence, it is categorical data.

STEP 17

"Travel time to school" - This is a measurement of time and hence, it is numerical data.

STEP 18

"Year level" - This is a level of education and can be considered as ordinal categorical data as it has a specific order.
So, the classification of the CensusAtSchool question topics into categorical and numerical data is as followsCategorical Favourite sport, Language mostly spoken at home, Opinions on environmental conservation, School post code, State/Territory live in, Travel method to school, Year levelNumerical Amount of money earned last week, Arm span, Birthdate, Concentration exercise (seconds), Dominant hand reaction time, Height, Hours slept per night, Foot length, Travel time to school
