Word scramble
Unscramble the letters and write each key term on the line.
1
OTW SPLAYHIC TSETSA
Storage keeps each bit as one of two physical conditions, such as charged or not charged, magnetised one way or the other, or a pit or a flat area. One condition is 0 and the other is 1.
2
LDCESO SV PNEO UTENSOIQ
A closed question gives fixed choices to pick from, like multiple choice or a rating scale. An open question lets people write their own answer, so it is harder to count.
3
ELASMP
The group of people you actually ask in a survey. A bigger, fairer ______ gives more trustworthy data than asking only a few friends.
4
TTCSEINSNO TDAA NRYTE
Typing each survey answer in its own cell, one row per person, using the same spelling and format every time (Yes, not yes or Y), and leaving the cell blank if there is no answer.
5
UTENU.AREPTPEMRIT()
A micro:bit block that returns the temperature reading in degrees Celsius as a number. You can show it with basic.showNumber() or store it in a variable.
6
EADROOTLGA.GGL()
Saves one row of named sensor readings, with a timestamp, in the micro:bit data log. Each call adds a new row, so use it in a loop to record readings over time.
7
AM_MTDH.TYA
The file on the MICROBIT USB drive that opens the data log. Use its Download CSV button, then open the CSV in a spreadsheet and check the column headings.
8
RELTUIO
A reading far from the rest or impossible, like -999. It may mean the sensor is faulty or in the wrong place, so check it before you use it.
9
ADAT ORTENRGEA
A tool that makes random sample data, with fields and rows you choose, to practise with when real data is not available. You can export it to a spreadsheet. It is test data, not real data.

1OTW SPLAYHIC TSETSA → two physical states — Storage keeps each bit as one of two physical conditions, such as charged or not charged, magnetised one way or the other, or a pit or a flat area. One condition is 0 and the other is 1.
2LDCESO SV PNEO UTENSOIQ → closed vs open question — A closed question gives fixed choices to pick from, like multiple choice or a rating scale. An open question lets people write their own answer, so it is harder to count.
3ELASMP → sample — The group of people you actually ask in a survey. A bigger, fairer sample gives more trustworthy data than asking only a few friends.
4TTCSEINSNO TDAA NRYTE → consistent data entry — Typing each survey answer in its own cell, one row per person, using the same spelling and format every time (Yes, not yes or Y), and leaving the cell blank if there is no answer.
5UTENU.AREPTPEMRIT() → input.temperature() — A micro:bit block that returns the temperature reading in degrees Celsius as a number. You can show it with basic.showNumber() or store it in a variable.
6EADROOTLGA.GGL() → datalogger.log() — Saves one row of named sensor readings, with a timestamp, in the micro:bit data log. Each call adds a new row, so use it in a loop to record readings over time.
7AM_MTDH.TYA → MY_DATA.HTM — The file on the MICROBIT USB drive that opens the data log. Use its Download CSV button, then open the CSV in a spreadsheet and check the column headings.
8RELTUIO → outlier — A reading far from the rest or impossible, like -999. It may mean the sensor is faulty or in the wrong place, so check it before you use it.
9ADAT ORTENRGEA → data generator — A tool that makes random sample data, with fields and rows you choose, to practise with when real data is not available. You can export it to a spreadsheet. It is test data, not real data.
